J. Cent. South Univ. Technol. (2008) 15(s1): 067-071 DOI: 10.1007/s11771-008-316-0 Effect of substrates on crystallization of high density polyethylene FAN Yu-run(范毓润), LIN Yuan(林 渊), RUAN Mian... of the substrates on the isothermal crystallization rate of a high density polyethylene(HDPE) were presented. Two methods were used to characterize the crystallization rate: the change of turbidity of the HDPE......
) were used to identify the crystal structure, the surface and cross-section morphology of the deposited ferroelectric films. The results show that the crystallization atmosphere has significant effect on determining the crystallization and ferroelectric properties of the BDT films. The film crystallized in nitrogen at a relatively low temperature of 650 ℃, exhibits excellent crystallinity......
