Research and application progress of trans-1,4-polyisoprene

trans-1,4-Polyisoprene(TPI) is thermoplastic crystalline polymer which has similar structure with nature rubber. Owing to its low melting point and high thermal stability,it is usually used in the area such as tire modification,medical materials and shape memory materials. Moreover,it can also be applied to fabricate conductive heating fibers,photothermal conversion function membranes,biological antifouling materials as well as foam materials. The production and modification methods of TPI are introduced. Research and application progress of TPI used as fibers,membranes,foams and shape memory materials are reviewed,while a perspective outlook of further application of TPI is outlined.
