    • An expanded polymeric web includes between about 0.1 and about 70 weight percent of a compound comprising nanoparticles. The expanded polymeric web includes between about 30 and about 99.9 weight percent of a generally melt processable polymer. The web also includes between about 0.0 and about 50 weight percent of a compatibilizer. The expanded polymeric web comprises a first region and a second region, the first region undergoing a substantially molecular deformation and the second region initially undergoing a substantially geometric deformation when the polymeric web is subjected to an applied elongation along at least one axis, and wherein the expanded polymeric web has a greater propagation tear resistance than an expanded polymeric web of the melt processable polymer alone.
    • 膨胀聚合物网包含约0.1至约70重量%的包含纳米颗粒的化合物。 膨胀聚合物网包含约30-约99.9重量%的通常可熔融加工的聚合物。 纤维网还包含约0.0-约50重量%的增容剂。 膨胀的聚合物网包括第一区域和第二区域,第一区域经历基本上分子变形,并且当聚合物网沿着至少一个轴线经受施加的伸长时,初始经历基本上几何变形的第二区域,并且其中 膨胀聚合物网具有比单独的可熔融加工聚合物的膨胀聚合物网更大的传播撕裂阻力。
