However, the synergistic effect and mechanism of CNTs and TP resin have not been attained. The interlaminar region of interleaved composites is too narrow and complex to be fully analyzed. Therefore, the layered resin structure composed of an interlayer and a matrix (epoxy) layer was prepared to model the interlaminar region in this study. The evolution of gradient structure developed by the layered structure in curing and the influence of presence of CNTs in interlayer were investigated based on morphology characterization. The results showed that epoxy resin gradually diffused into the interlayer, resulting in the concentration gradient and the resultant gradient phase structure. The presence of CNTs in hybrid interlayer hindered the resin diffusion and consequently hindered the formation of dual-phase structure, which was not conducive to the toughness improvement. The inappropriate high temperature was not recommended due to the effect of facilitating diffusion, probably resulting in the formation of excrescent epoxy layer in the interlaminar region and undesired mechanical performance. This study conducted experiments on resin system to simplify the interesting subject and the results will help to develop the synergistic mechanism of TP resin and nanoparticles.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139648593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These nanocomposites combine biopolymers, natural polymers derived from renewable sources, with nanoparticles or other nanoscale materials to create materials with enhanced properties and functionalities. Biopolymers that are used to make bio-nanocomposites are cellulose, alginate, chitosan, starch, polylactic acid (PLA), polyhydroxyalkanoate (PHA), polyhydroxybutyrate (PHB), etc. These have different properties, and they can be used in several types of treatments. Scaffolds frequently employ polylactic acid-gelatin, nanocellulose, and chitosan. Studies have shown that some special types of hydrogel films have proven beneficial in anticancer treatment. Synthetic and naturally occurring substances such as PLA, polyvinyl alcohol (PVA), guar gum, and chitosan are employed in the drug delivery system. Nanocomposites such as silver nanoparticles with chitosan, sulfated polysaccharides, and thyme-loaded carrot nanocellulose or starch biopolymer nanocomposites have been used to stop bacterial development. This review article provides a comprehensive insight into biopolymer-based nanocomposites and their uses. Also, it has been incorporated into fields such as biosensors, bioimaging, blood clotting, immunomodulation, antibacterial and antiviral drugs, and food packaging. Hence, the primary objective of this review is to provide an overall perspective on biopolymer nanocomposites in nanomedicine.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139583469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the poor mechanical properties of traditional synthetic hydrogels limit their applications in biological fields. Herein, a series of tough physical hydrogels have been prepared by micellar polymerization, in the existence of sodium bromide (NaBr), using methacrylic acid (MA) and stearyl acrylate (SA) as monomers, cetyltrimethyl ammonium bromide (CTAB) as cationic surfactant. The hydrogels exhibit excellent mechanical properties: modulus, toughness, and tearing fracture energy up to 7.8 MPa, 34 MJ m−3, and 16,600 J m−2, respectively. Moreover, it was found that the toughness of the hydrogels can be modulated in a very wide range by different post-treatments, e.g., dried/reswelling, freezing/thawing, or heated treatments. After post-treatments, the elastic physical hydrogels even turn into brittle plastics: modulus and toughness vary by 3 and 4 orders of magnitude, respectively. The mechanism for this wide tunability is attributed to the change of electrostatic attraction, crystallization, and phase separation during post-treatments.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139508166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mechanical surface preparation has a great influence on the chemical properties (increasing surface energy and creating a stronger bond) and mechanical properties (creating mechanical interlocking and increasing friction) of adhesive bonding. Hence, the response surface method was employed to examine the influence of groove number (1, 3, 5), groove angle (0, 45, 90°), groove shape (V-shape, square, concave), and joint type (metal–metal, metal–composite, composite–composite) on the tensile strength of the bond. To simulate the bond behavior of Al/GFRP under different parameter conditions, the cohesive zone model was used to consider the crack growth. Optimization results obtained by the desirability function method showed that the maximum bond strength was achieved with a groove number of 1, groove shape of square, groove angle of 0°, and metal–metal joint type. The optimization results predicted by the desirability function and finite element analysis were in good agreement with those obtained by experimental tests.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139422831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, using structured statistical methods, analysis of variance, and response surface methodology, study the effects of various molding variables on material morphology and properties and determine the most important molding variables and their interactions. Finally, the associated experimental data are fitted by the least squares minimization program, and the relevant dimensionless equations are obtained. The purpose is to objectively analyze the influence mechanism of molding parameters on SR-SPCs and establish a mechanism model. It was found that temperature change was the most important factor affecting the morphology and mechanical properties. The degree of molecular orientation is the most important factor to determine the tensile strength and elastic modulus of the sample. The change of crystallinity is the most important factor related to the elongation at break. By establishment relevant dimensionless equations, the influence of molding parameters on the mechanical properties of SR-SPCs, such as tensile strength and elastic modulus, was preliminarily studied.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139421463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these shortcomings, this study used hybrid graphene nanoplatelets (GN) and titanium nitride (TiN) nanoparticles to significantly enhance the wear resistance and thermal stability of UHMWPE. The nanocomposites were prepared by solvent mixing and hot compression process. Scanning electron microscope showed uniform dispersion of the nanoparticles in the UHMWPE matrix. The developed UHMWPE showed improved wear resistance and thermal stability relative to the pure UHMWPE. For instance, the wear rate reduced from 6.7 × 10−3 mm3 N−1 m−1 and 3.67 × 10−2 mm3 N−1 m−1 for pure UHMWPE to 2.687 × 10−5 mm3 N−1 m−1 and 1.34 × 7 × 10−4 mm3 N−1 m−1 for UHMWPE–2 wt% GN–10 wt% TiN at applied loads of 10 N and 20 N respectively. This is about 100 % increment in wear resistance at the respective applied loads compared to the pure UHMWPE. The thermal stability of the fabricated nanocomposites was studied using the thermogravimetric analyser (TGA). The addition of nanoparticles significantly reduced the thermal decomposition of UHMWPE matrix. The enhanced properties of the UHMWPE–GN–TiN nanocomposites may be attributed to the network structures formed from the dispersion of the GN and TiN nanoparticles in the UHMWPE matrix with promoted molecular chains interlocking.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138572039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
