Static Charge Reduction of PAN from Blending with Hydrophilic Polymers
친수성 고분자와의 용액 블렌딩에 의한 PAN의 대전성 개선
Abstract
To increase the moisture regain and thereby to reduce the static charge of polyacrylonitrile (PAN), blends of PAN with hydroxypropyl cellulose(HPC), a hydrophilic polymer, were prepared. Results indicated a significant increase in moisture regain and drastic drop in static charge to approximately 1/12 of PAN at 4% HPC. However, the tensile strength of blend decreased with HPC content due mainly to incompatible nature of the binary blends. Addtion of cyanoethylated HPC(CEC) or polyacrylonitrile-g-HPC(GHP) to the PAN/HPC binary system reduced the dispersed phase domain to appromaximately 1/10 of the binary blends and resulted in an increased tensile strength to a level close to PAN.
