Oxygen degradation takes place mainly in the amorphous phase into which oxygen diffuses. This leads to oxidation (formation of hydroperoxides) and next the chains scission. The polymer becomes brittle and breaks down into small pieces (e.g. microplastics). The crystalline phase is more difficult to access for oxygen that initiates the thermo-oxidation process. An increase in the crystallinity degree and a decrease in the viscosity of the solutions diluted in p-xylene as a function of the degradation time were observed. The number of iPP chain scission (change in molecular weight) as a function of degradation time was also calculated. These values depend on the polymer initial crystallinity degree and its supermolecular structure.","PeriodicalId":20319,"journal":{"name":"Polimery","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42850821","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}

The ink was obtained by the ultrasonic dispersion method by mixing PEDOT, PSS and SNP and then adding co-solvents. The ink was applied to the cotton fabric by printing method. The structure, electrical and functional properties of fabrics were investigated. The increase in electrical conductivity was found as a result of the phase separation between PEDOT and PSS due to the use of co-solvents.
