Molding and Application of Ultra-high Molecular Weight Polyethylene Porous Materials
Ultra-high molecular weight polyethylene(UHMWPE)porous materials are widely used in envi-ronmental,energy and medical fields due to their excellent chemical stability and high specific surface area.In this paper,three kinds of porous UHMWPE materials with different morphologies are introduced,and the characteriza-tion methods of several key indexes of porous materials are also introduced.The common forming methods of differ-ent types of UHMWPE porous materials(tensile method,thermal phase separation method,pore-forming agent method,powder sintering method,foaming method)and the current research results at home and abroad are de-scribed in detail.On this basis,the advantages and disadvantages of various forming methods are analyzed,and the future research direction of UHMWPE porous materials is put forward.
