1. A reinforced polyolefin composite comprising
a polyolefin and fillers dispersed in the polyolefin, wherein the fillers comprise a rigid micro filler, and at least one nano filler, wherein the rigid micro filler is rigid in that it has a Young's modulus that is higher than that of the at least one nano filler, and wherein the at least one nano filler comprises positive charged clay particles having a layer of silica disposed thereon, wherein the positive charged clay particles having a layer of silica disposed thereon are obtained by surface treating clay particles with an acrylate, and treating thereafter with an organo silane and an organo silicate in the presence of a basic liquid catalyst.
