Researchers are in a race to develop value-added products from natural renewable sources and discarded waste materials. Studies indicate several hurdles while trying to provide ecologically friendly materials for product manufacturing over the years. Natural materials are more readily available, biodegradable, more affordable, have less processing health hazards, and are more environmentally friendly than synthetic materials. As the price of commercial polymers decreased, the incorporation of fillers became increasingly necessary for technical reasons.. The market for polymers can actually be expanded by appropriately combining fillers and polymers to produce a wide range of qualities in these two components. This review provides an overview on a variety of organic and inorganic fillers which were incorporated into the polymer composites and their influence on the physical, chemical, mechanical, thermal, and electrical properties of polymer composites by various characterization methods and their In fact, it is possible to achieve a wide range of qualities in these two components by appropriately combining polymers and fillers, which expands the market for which polymers may be employed.application scopes.

Therefore, it is necessary to reduce the dosage of ZnO in order to minimize its environmental impact. In this study, we applied ZIF-8, a zinc-based metal–organic framework, as a vulcanization additive in natural rubber. and it was found that ZIF-8 could promote the rubber vulcanization reaction by adsorbing sulfur, promoting sulfur ring-opening, and providing different ligand interactions of Zn<sup>2+</sup>.

Herein, a hyperbranched polyborosiloxane (HPSiB) flame retardant was synthesized via a simple one-pot transesterification as a multifunctional additive for cyanate ester (CE) resin. The HPSiB with many active terminals features good compatibility with the resin matrix, while catalyzing the curing reaction that conducts at a lower temperature. With as little as 2 wt% HPSiB incorporated, the HPSiB/bisphenol A cyanate ester (BADCy) resin achieves a UL-94 V0 rating and 32.4% LOI value, and its peak heat release and total smoke production are simultaneously reduced. Its flexural strength and impact strength were significantly enhanced by 30.0% and 85.4%. Besides, the minimum values of dielectric constant and loss can reach 2.77 and 0.0024 at 10 GHz, which are, respectively, reduced by 7.9% and 88.5%.

Recently, the World Health Organization (WHO) has identified sepsis as a global health priority, attributing most sepsis-related deaths to the underlying infection. Sepsis is a complex disease that manifests in various ways, depending on factors, such as pathogen involved, mode of transmission, and the patient's immune competence. This study focuses on synthesizing zinc oxide (ZnO) through an in-situ precipitation method and employing a solution-based technique to coat the inorganic ZnO nanomaterial with the antimicrobial drug fluconazole (FLZ), resulting in a FLZ-ZnO composite. Further enhancement is achieved by modifying the composite with poly(vinyl alcohol) (PVA) to improve mechanical strength, physicochemical characteristics, and the interfacial network between ZnO and FLZ. Characterization through X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), particle size distribution (PSD), and thermo gravimetric analysis (TGA) confirms the synthesized compounds are stoichiometric in nature.

However, their use in 3D printing has been limited due to challenges such as excessive softness, shrinkage, warpage, and poor mechanical properties. In this study, two strategies were employed to enhance the performance of POEs in 3D printing. First, POE was blended with 10%, 30%, and 50% percentages of linear low-density polyethylene (LLDPE) to improve the material's mechanical properties and printability. Second, a specialized printer called a pneumatic feeding fused granule fabrication (FGF) printer was used. This printer allows for the direct printing of material granules, eliminating the need for filaments and resolving filament-related problems. To evaluate the quality of the printed parts, tensile tests, dynamic mechanical thermal analysis (DMTA), and scanning electron microscopy (SEM) imaging were conducted. The printed parts showed desirable tensile properties (with approximately 3000% elongation at break and approximately 12 MPa tensile strength). Compression tests were also conducted on cubic structures with varied composition ratios and printing patterns such as grid, triangle, and honeycomb. The main purpose of this research was to explore the energy absorption capabilities of the printed blends. The results of our study showed that blending POE with LLDPE improved printability, tensile strength, energy absorption, and compressive properties. The blend with 50% LLDPE and honeycomb structure exhibited the best compressive and energy absorption properties.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Blending of POE and LLDPE using melt mixing with three different blending ratios.</li>\u0000 \u0000 <li>Successful 3D printing with the fused granule fabrication technique.</li>\u0000 \u0000 <li>Investigating mechanical properties, microstructure, and thermal analysis.</li>\u0000 \u0000 <li>125% increase in ultimate tensile strength by increasing LLDPE.</li>\u0000 \u0000 <li>Achieving the highest energy absorption for the 3D printed honeycomb structure.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":17662,"journal":{"name":"Journal of Vinyl & Additive Technology","volume":"30 4","pages":"983-996"},"PeriodicalIF":3.8,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139978067","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}

Thus, this research addresses an efficient treatment agent from natural rosin acids (R) and dapsone (D) with variable sublethal proportions of synthesized titanium dioxide nanoparticles (TiO<sub>2</sub> NPs) (i.e., 0.1%, 0.3%, and 0.6%) for modifying kilim fabric (KF) using a dip-coating method. The nanostructure of prepared TiO<sub>2</sub> nanoparticles and their particle size were examined by x-ray diffraction (XRD) and Zetasizer analyzer. The data showed that the majority of prepared TiO<sub>2</sub> oriented to a rutile-type structure with an average hydrodynamic diameter of 48.30–49.65 nm. The KF-R/D-0.3% TiO<sub>2</sub> NPs specimen provided the best tensile properties reached ~3192 N compared with the untreated KF (i.e., 1125 N). This finding confirmed by SEM observations. Whereas, the specimen containing decorated TiO<sub>2</sub> NPs (i.e., 0.6%) possessed higher flammability resistance property compared with other specimens. Moreover, XRD and FTIR results for treated KF specimens demonstrated the significant role of TiO<sub>2</sub> NPs, which react with KF keratin either by new linkages or through chelating geometry to form a compact KF matrix. This contributed to enhance the tensile and flammability properties. Additionally, a great achievement in antibacterial properties occurred when TiO<sub>2</sub> NPs used and their inhibitory zones were 18–36 mm, depending on the bacteria and specimen type.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Novel treatment of KF fabric-based bioagents with sublethal contents of TiO<sub>2</sub> NPs was successfully prepared by dip-coating route.</li>\u0000 \u0000 <li>The tensile force and flammability of treated KF fabric were greatly enhanced.</li>\u0000 \u0000 <li>A great achievement in antibacterial activity was noticed when TiO<sub>2</sub> added.</li>\u0000 \u0000 <li>These treated fabrics have excellent possibility for use in conserving cultural heritage.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":17662,"journal":{"name":"Journal of Vinyl & Additive Technology","volume":"30 3","pages":"855-867"},"PeriodicalIF":2.7,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139956916","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}
