Abstract

Nylon 6 and nylon elastomer were prepared by anionic polymerization route. Nylon elastomers, composed of hard segment of polyamide(PA) and soft segment of polyether(PE), were synthesized by use of TDI terminated polyol with caprolactam. The morphology of the electrospun webs of nylon and nylon elastomers, observed by FE-SEM, showed that the porous electrospun web was composed of nanofibers, whose diameter were in the range of 100 to 180 nm. Their behavior of melting and crystallization and the chemical structure of nylon elastomers were investigated by DSC and ATR FT-IR. Result of tensile testing indicated that nylon has higher tensile strength and lower elongation than nylon elastomers. Atmospheric plasma(APP) with $O_2$ and $N_2$ as reactive gas modified the surface of electrospun nylon and electrospun nylon elastomers allowing them higher hydrophilicity, while APP with $CH_4$ as reactive gas modified the surface of polymers allowing higher hydrophobicity.
