An in situ surface modification method of ultra-high molecular weight polyethylene fiber on the basis of dry gel-spinning technique

A novel in situ surface modification strategy of ultra-high molecular weight polyethylene (UHMWPE) fiber is proposed, which is related to the dry gel-spinning technique and the directional entrapping modification. The surface modification, with poly (ethylene oxide) monooleate (OEO) as the modifier,...
