Synergistic Hydrophilic Modification and Performance Enhancement of Polyphenylene Sulfide Nonwovens via Oxidative Pretreatment/Dopamine Deposition
摘要
Abstract
To improve the hydrophilicity of polyphenylene sulfide(PPS)nonwovens,a new type of poly-phenylene sulfide/polyphenylene sulfide sulfone(PPS/PPSS)layer was prepared on the surface of PPS nonwo-vens by the oxidation process.Different oxidant concentrations were used to oxidize PPS nonwovens and the opti-mal oxidation process was explored.Dopamine was then deposited on the surface of the PPS nonwovens to pre-pare PPS/PPSS/polydopamine(PDA).The experimental results showed that dopamine was deposited after oxi-dation pretreatment,the wettability modification effect of PPS nonwovens was better,the contact angle was reduced to 42.6°,the water absorption increased to 272.22 ml/m2,the water absorption rate reached 519.4 ml/m2/s,and the water vapor transmission rate reached 287.4 g∙mm/m2∙day∙pa.In addition,after the co-treatment of oxidation pretreatment/dopamine deposition,the comprehensive performance of PPS nonwovens such as alkali re-sistance and thermal stability improved,the breaking strength increased to 1721.3 N,and the elongation at break increased by 21.4%,and the friction resistance reached level 4～5,which broadened their potential applications in special fiber paper,working condition clothing and hydrogen separator by water electrolysis.关键词
