Polymeric porous substrates including porous particles

包含多孔粒子的聚合多孔基材

Abstract

A polymeric porous substrate is described. The substrate may be used as battery separator or in other industrial applications. The polymeric porous substrate is formed from a polymer such as a polyimide or polyetherimide that, in the absence of porous particles, forms a skin when cast into a substrate. The polymeric porous substrate also includes porous particles.
本发明描述了聚合多孔基材。所述基材可以用作电池隔膜或用于其它工业应用。所述聚合多孔基材由在没有多孔粒子的情况下当浇铸成基材时形成表皮的聚合物形成,所述聚合物例如聚酰亚胺或聚醚酰亚胺。所述聚合多孔基材还包含多孔粒子。
