Promoted Chain Diffusion of UHMWPE/HDPE Blend by High Temperature Treatment

Abstract:

Ultra high temperature treatment was used to promote the molecular chain diffusion of UHMWPE/HDPE blend. At the same time, melt blended sample and solution blended sample were also prepared for a comparison. The phase morphology of the samples observed by scanning electron microscope (SEM) showed that the difference between HDPE and UHMWPE became smaller after high temperature treatment. While the UHMWPE particle could not be observed in solution blending samples. The results of rheological test showed that the elastic modulus and complex viscosity of treated samples are higher than that of untreated samples but still below the viscosity of solution blending sample. The results deem, high temperature treatment indeed promoted the chain diffusion of UHMWPE/HDPE blend and a good fusion between HDPE and UHMWPE is obtained as a result
