Research progress on surface modification and application status of UHMWPE fiber

Abstract

Abstract Ultrahigh molecular weight polyethylene (UHMWPE) fiber is a high-performance material with superior properties of high strength and modulus, low density, wear resistance and corrosion resistance. But the development of UHMWPE fiber reinforced polymers is hindered due to its inert inactive surface and poor interfacial adhesion with polymer matrix. This work presents the research progress on surface modification techniques, including ‘dry’ treatment, strong oxidant treatment, chemical grafting and coating, of UHMWPE fiber and the mechanisms of the improvement on surface properties and interfacial adhesion strength between the UHMWPE fiber and the polymer matrix. Application status of UHMWPE fiber such as aerospace, ocean engineering and individual protection is introduced.
