The SMO although is medicinally significant yet finds limited applications in medical and functional textiles because of its less stability and high volatility under ambient conditions. Nevertheless, its encapsulation in chitosan may enhance its stability and applicability for the said purpose. The SMO encapsulating chitosan microstructures were characterized using different analytical techniques and applied on cotton fabric through a green crosslinking of citric acid. The treated fabric revealed successful adhesion of microcapsules onto its surface confirmed via SEM and FTIR analyses. There observed a slight decrease in tensile strength of treated fabric; that, however, improved crease recovery behavior, and good antibacterial activity in response to broad-spectrum bacterial strains by reducing their 99% population; whereas, the stiffness of such fabric exhibited somehow increasing trend. Hence value-added multifunctional textiles produced, herein, may provide both surface and antibacterial activity for potential medical and healthcare applications without compromising their comfort properties.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"64 5","pages":"456 - 466"},"PeriodicalIF":1.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S0965545X22700158.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5121622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advisability of using one-pot blending procedure for the synthesis of composites from polymers processed by extrusion is substantiated. Formation of the intercalated structure of the nanocomposite in the system under consideration is verified experimentally. The nanostructure of an organoclay in the composites obtained by the conventional method (polymer blending with organoclay) and the one-pot procedure (polymer blending with natural clay and organomodifier) is found to be almost the same. It is shown that the physicomechanical characteristics of the nanocomposites synthesized by different methods are also similar. Resistance of organoclay structure formed in the polymer composite against sodium chloride aqueous solution is investigated by X-ray diffraction. It is revealed that the structure of the nanocomposites obtained by different methods remains almost unchanged during their swelling in water and subsequent drying which provides evidence that modification of the clay during blending with the polymer matrix is complete and the composite does not contain nonmodified clay swelling in water.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"64 4","pages":"318 - 325"},"PeriodicalIF":1.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5163930","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}

Different mass fractions of block copolymer have been used to produce composites material. The structural, chemical and morphological analyses of composites have been done. Differential scanning calorimetry and thermogravimetric analysis results indicated that the addition of supporting material (block copolymer) improves the thermal stability without much affecting the phase transition temperature of paraffin. The paraffin leakage in composites is analyzed by mass loss over thermal cycles in an oven at 80°C and the best performance has been achieved for 20 wt% of block copolymer into the composite. The thermal reliability of this sample has been investigated after 100 thermal cycles. Overall inspection of results suggested that the prepared composite is the most appropriate shape-stable phase change material for thermal energy storage applications because of their acceptable energy storage capacity, good thermal stability and reliability, physical and chemical compatibility, low cost and easy synthesis process.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"64 4","pages":"308 - 317"},"PeriodicalIF":1.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5105958","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}

Solutions of binary mixtures of the branched PAN with the industrial linear polymer in dimethyl sulfoxide with different ratio of the components have been prepared; their rheological behavior has been investigated. It has been shown that the introduction of the branched polymer in a solution of linear PAN allows significant decrease in the mixed solutions viscosity at equal total fraction of the polymer. The addition of branched PAN in a solution of the linear PAN has increased the total concentration of the polymer in the system favoring the increase in the viscosity of the mixed solution, but the viscosity has been significantly lower than this of the equally concentrated solution of the linear polymer. Investigation of the frequency dependences of the components of complex shear modulus of these solutions has revealed that the increase in the viscoelastic properties is mainly due to the increase in the elasticity modulus. Exponent of the frequency dependence of the loss modulus in the terminal zone has not been changed, whereas this of the elasticity modulus has been decreased to 0.4 over the entire range of the ratio between the branched and linear PAN. The specific relaxation time has been decreased with the increase in the fraction of linear PAN. Thermal behavior of linear and branched PAN has been investigated by means of DSC.
