【Abstract】 Blends of inorganic nano zirconium dioxide(ZrO-2) and poly(ether-sulfone)(PES) were prepared by mechanical blending. Their mechanical, thermal and electrical properties were investigated. Compared with pure PES, this kind of organic/inorganic nano-composite exhibit a better electrical property, lower coefficients of thermal expansion, as well as a similar thermal properties. The mechanical properties are composition-dependent.更多还原
