These complications are the most pronounced in the case of a hydrophilic polymer which cannot melt without decomposition (as polysaccharides) used as the filler. In this study, we have taken advantage of the solvent-free extrusion method both to modify the chitosan chemical structure in order to impart amphiphilic properties and to mix the obtained derivatives with polyethylene. The influence of the processes parameters, the presence of plasticizer, and the filler content on the thermal and mechanical properties of the composite film materials as well as their morphology has been investigated. It has been found that the introduction of hydrophobic fragments in the structure of chitosan insignificantly improved the mechanical properties of the materials in comparison with the pristine polysaccharide. A more significant effect has been caused by simultaneous introduction of the plasticizer, affording the materials with uniform morphology and improved plasticity.","PeriodicalId":740,"journal":{"name":"Polymer Science, Series C","volume":"66 1","pages":"46 - 54"},"PeriodicalIF":1.6,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The raw materials for powdered cellulose are waste from the woodworking and agricultural industries, as well as processed products from the pulp, paper, and textile industries. Historically established mechanical, physical, chemical, and biological methods are presented in the review with information on the possibilities of using additional stages, for example, the steam-explosive method. Information is provided on comparative structural studies of the presence of functional groups of lignocellulosic raw materials and powdered celluloses obtained from them, taking into account the supramolecular structure and residual lignin. It is shown that powdered cellulose can be widely used in sovereign technologies of the pharmaceutical and cosmetic industries as binders and emulsifiers and can be processed into ethers and esters, as well as into fibers (through solutions). Nonaqueous solutions of cellulose and mixtures of cellulose with synthetic polymers open up the possibility of creating carbon fiber materials and composites (uniquely combining high strength, chemical and heat resistance, as well as electrical conductivity and low density), which are important in scientific and practical terms in expanding the range of products of the textile and medical industries, as well as a variety of equipment with unique properties for the automotive industry, rocket and missile engineering, and various special-purpose equipment. The development of these technologies is, of course, interdisciplinary.","PeriodicalId":740,"journal":{"name":"Polymer Science, Series C","volume":"66 1","pages":"55 - 67"},"PeriodicalIF":1.6,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the composites, the ratio ultrahigh molecular weight PE : lower molecular weight PE (polyethylene) is varied with the molecular weight of PE being constant or the molecular weight of PE is varied with the ratio ultrahigh molecular weight PE : lower molecular weight PE being constant. In this case, the lower molecular weight PE is the external layer on the surface of composite particles, while the ultrahigh molecular weight PE occurs directly on the surface of filler particles. In both cases, with an increase in the fraction of polyethylene in the two-layer coating in pressed composites, the degree of crystallinity increases and the lamella parameters change. The mobility of polymer chains in the intercrystalline amorphous layer alters. Creation of two-layer coatings ultrahigh molecular weight PE/lower molecular weight PE allows modification of the deformation–strength properties of the composites. An increase in the content of polyethylene in the composites is accompanied by a considerable increase in the elongation at break and the elastic modulus of the composites while the breaking stress decreases.","PeriodicalId":740,"journal":{"name":"Polymer Science, Series C","volume":"66 1","pages":"30 - 38"},"PeriodicalIF":1.6,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
