Phthalic anhydride was used to corrode the aramid fibers (AFs) in order to improve the interfacial compatibility between AFs and recycled polyethylene terephthalate (R-PET). Besides. the intrinsic viscosity and the mechanical properties of the composites of AFs/R-PET could be improved to realize the transformation from waste products to engineering plastics because phthalic anhydride ... https://www.pomyslnaszycie.com/
