Abstract

This review summarizes the current status and recent advances in the condensed-state chain structure characteristics

modification optimization strategies

and processing technologies of ultra-high molecular weight polyethylene (UHMWPE). Furthermore

factors such as temperature control

antioxidant incorporation

irradiation sterilization

melt pretreatment

foaming

crosslinking

stepwise stretching

and composite modification strategies were systematically investigated

and the regulatory rules governing the relationships between these factors and molecular chain crystallinity

chain entanglement density

orientation degree

and lamellar morphology were elucidated. UHMWPE produced via different processes exhibits distinct applications

such as rubber modification

battery separators

artificial joints

and high-strength lightweight materials. Based on these summaries

this review provides valuable insights for future exploration of condensed-state structures of UHMWPE

processing systems

and development of high-value

functionalized

and differentiated applications.
