%A HE Chun-Xia, LU De-Rong, XIAO Sheng-Ming %T Dispersion Characterization of PTFE Composites Filled with Different Nano-particles %0 Journal Article %D 2011 %J Journal of Shanghai Jiao Tong University %R %P 1411-1415 %V 45 %N 09 %U {https://xuebao.sjtu.edu.cn/CN/abstract/article_39772.shtml} %8 2011-09-30 %X The sweep electron microscopy (SEM) image was processed and segmented to nano Si3N4, SiC, and AlNmodified PTFE composites. Agglomeration degree and dispersed uniformity of the nano-particles in the image were quantatively segmented using particle dispersion method. The results show that the dispersed uniformity of these three nano-particle decreases as follows: nanoSiC, and nanoSi3N4, nano-AlN. Under the condition of 7% of nano-Si3N4 and nano-SiC and 5% of nano-AlN, the dispersed uniformity in PTFE is better. By processing coupling agent NDZ, the agglomeration degree of nano-particles in PTFE will decrease, the dispersed formity of nanoSi3N4 and nano-SiC in PTFE will be improved, but the dispersed formity of nano-AlN in PTFE will decrease.
