The SiO<sub>2</sub> NPs are characterized by FTIR, SEM analysis, and zeta potential measurements. SiO<sub>2</sub> NPs embedded PSF and PVDF membranes were characterized by FTIR, SEM analysis, contact angle, water permeability, oil rejection measurements, and recycling experiments. The results of the experiments showed that oil rejection reached maximum values of 92.2% for 2 wt% PSF/SiO<sub>2</sub>, and 94.1% for 2 wt% PVDF/SiO<sub>2</sub> membranes. The experimental results demonstrate that the incorporation of SiO₂ nanoparticles enhances the oil rejection efficiency of two distinct membrane types, exhibiting notable performance disparities contingent on the selected membrane material. This methodology achieves a recycling rate of over 90% for oil waste, signifying a substantial advancement in environmental protection and sustainable development. Consequently, the membrane production technique is regarded as an efficacious approach for the management and recycling of oil waste.</p>\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 11","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362994","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 resources for SAPs synthesis are cellulose, chitin, chitosan (as natural-based), and polyacrylate (as synthetic-based). Likewise, semi-synthetic SAPs have also been explored by graft copolymerization and crosslinking between natural and synthetic resources. Several key properties in SAPs are absorption capacity, biodegradability, antibacterial capabilities, swelling properties, and grain size. It is found that cellulose-based SAPs have high water absorption capacity and biodegradability, chitosan-based SAPs are superior in biodegradability and antibacterial capabilities, and polyacrylate-based SAPs are eminent in water absorption capacity. As a further recommendation, cellulose-based SAPs from plants or seaweeds can be a solution to replace synthetic polymer materials that are not environmentally friendly while supporting sustainable agricultural needs.

Electron beam lithography (EBL) studies demonstrate that the PGM photoresist functions as a positive tone photoresist with commendable sensitivity (27.9 μC/cm<sup>2</sup>) and contrast (6.53). When compared under similar conditions, with equal amounts of PAG and identical processing, the PGM photoresist exhibited superior pattern fidelity, ease of handling, and higher line resolution (25 nm) relative to the triphenyl sulfonium triflate (TPS-OTF) blend polymer (PG-T) photoresist. This enhancement is probably caused by anionic PAG directly attaching to the polymer backbone, which mitigates acid diffusion during the post-exposure baking (PEB) process. Moreover, the PGM photoresist obtained a pattern of 37.5 nm at 50 mJ/cm<sup>2</sup> in the EUVL test.
