To regulate the size of the pores of PES and prevent clogging, different qualities of poly(ethylene glycol)38-block-poly(propylene glycol)8 (PEG-PPG) were introduced and screened for the best ratios. Further introduced synthesized nitrogen-doped titanium dioxide (N-TiO2), anti-fouling and photocatalytic PES ultrafiltration membranes (N-TiO2@M) were prepared. N-TiO2@M3 exhibited bovine serum albumin rejection rate of 93.8% and achieved a methylene blue photocatalytic efficiency of 95.3% after 120 min of operation. Furthermore, N-TiO2@M4 showcased a water contact angle of 41.0°. Notably, the pure water flux of N-TiO2@M4 surged by 499.3% compared to that of PES membrane. The fouling resistance ratio for membrane flux witnessed an increase from 70.0% to 82.7%, demonstrating the enhanced durability of N-TiO2@M4. Moreover, the comprehensive analysis for N-TiO2@M4 revealed a total contamination rate of 40.2%. The irreversible contamination rate of N-TiO2@M4 after 1 h of ultraviolet light (UV) cleaning was 5.7%, and the irreversible contamination rate after 1 h of visible light irradiation was 6.7%. The method for mixing N-TiO2 and PEG-PPG is straightforward and convenient, offering potential for the development of N-TiO2@M with resistance to pollution and degradation in visible/UV light.","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"141 47","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the wet mixing process increased the fiber length by more than 300% compared to the open mixing process, while the fragmentation rate of the hollow glass beads was reduced by 94.4%, these effectively maintained the structural integrity of the fibers and the hollow glass microsphere filler. By using the wet mixing process, the density of EPDM composite materials can be reduced by about 20%, and the tensile strength and ablation resistance of these composites were also significantly improved.

Due to the high reactivity of melamine, particle agglomeration can occur. To tackle this issue, this study focuses on optimizing the quantity of emulsifiers to achieve the best microcapsules with 15% melamine in the shell structure without particle agglomeration. The impact of melamine content and the quantity of emulsifier on the morphology of the synthesized microcapsules, the reaction yield, core content, and the hardness of the microcapsule shell were investigated. The presence of tung oil in melamine-urea-formaldehyde microcapsules was proven by Fourier transform infrared spectroscopy (FT-IR). Field emission scanning electron microscopy (FESEM) revealed the spherical morphology of the capsules with a mean diameter of 2.29 μm. UV–vis analysis and nano-indentation tests were used to evaluate the core content and the hardness of the result microcapsules, respectively. Finally, one sample, as the best microcapsule, was dispersed in an alkyd-based resin in the amount of 1, 2.5, and 5 wt% and applied on a steel substrate for its ability to prevent corrosion. The study also highlights the adverse effect of excessive capsule usage in the resin, as demonstrated by reduced resin adhesion to the substrate, according to electrochemical impedance spectroscopy (EIS) and salt spray tests. The study found that the best long-term anticorrosion properties are achieved by including 1 wt% of microcapsules in an alkyd resin.","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"141 45","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that PE and EPR cannot form CSRP if PE melt flow index (MFI) is lower than about 0.3 g/10 min. As a result, the impact fracture of PP/PE/EPR composite is brittle. If PE MFI is higher than 0.3 g/10 min, PE and EPR can form CSRP, leading to the ductile impact fracture of PP/PE/EPR composite. Interestingly, upper limit content of PE for the formation of CSRP depends on the type and viscosity of PE. For HDPE, upper limit content of PE tends to increase with the increase of its MFI, whereas it drops considerably for LLDPE. Understanding these relationships provides insights into optimizing the selection of core types and viscosity for enhancing the mechanical properties of polymer composites with core-shell structure. This may potentially guide the development of cost-effective and high-performance polymer composites.","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"141 46","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, mesoporous bioglass (MBG) was synthesized using a two-step acid-catalyzed self-assembly method, and a novel hemostatic sponge (MBG/CH/GEL) was prepared by combining chitosan (CH), gelatin (GEL), and MBG using a freeze-drying method. The characteristics and hemostatic effects of the MBG/CH/GEL composite hemostatic sponge were analyzed and evaluated. Research has shown that the high specific surface area of MBG (730 m2/g) provides more blood cell adhesion sites during hemostasis, resulting in a low hemolysis rate, favorable swelling rate, and porosity of the hemostatic sponge. Additionally, MBG can release Si4+ and Ca2+ ions during hemostasis, giving the composite hemostatic sponge excellent cell compatibility and promoting cell growth. Compared with commercially available gelatin hemostatic sponges, it cannot only quickly stop bleeding but also has a greater compressive strength (212.07 kPa) and adhesion strength (11.54 ± 0.16 kPa), making it suitable for use in hemostasis of incompressible wounds. Furthermore, the composite hemostatic sponge exhibited significant antibacterial effects against Staphylococcus aureus and Escherichia coli. These results indicate that the MBG/CH/GEL composite hemostatic sponge, which is a hemostatic material, has promising applications.","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"141 47","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of PBAT-MA on the tensile properties, rheological properties, morphology, and dynamic mechanics of PBAT/PBAT-MA/TPS blends were studied in detail. Rheological results revealed that the interaction between PBAT-MA and TPS enhanced the segment entanglement ability and improved the compatibility of the blends, which enhanced the tensile properties of the blends.

Herein, it focuses on the effects of CB content on the morphology, filler network structure, and properties of the TPV/CB composites. As observed by morphological studies, CB nanoparticles are interconnected and aggregated to form a dual network structure of rubber and CB particles in the composite. With the increasing CB content, it's demonstrated that dual networks have enhanced and shifted to rigid. Consequently, the hardness, thermal stability, and oil resistance of TPV/CB composites are improved, with a 104% elevation in the stress at 300% strain. The flowability in the molten state, toughness (the elongation at break decreased from 690% to 310%), and elasticity deteriorated by oversized (0.5 ~ 1.2 μm) CB agglomerates and rigid rubber particles.
