The result of TEM showed after the treatment by ultrasonic wave and silicone coupling agent, nano-meter palygorskite powder could disperse uniformly in the complex material.
TEM表明：通过超声波分散和硅烷偶联剂处理，纳米坡缕石粉体在复合材料中分散均匀。

But silica disperse in rubber difficult, although silane coupling agent has useful function in the white silica's dispersion and reduce the Mooney viscosity, but it also increased the elongation.
