摘要： The linear low density polyethylene nanocomposite fibers are formed from a linear low density polyethylene matrix having carbon nanotubes embedded therein. The addition of the carbon nanotubes enhances the overall toughness of the material, resulting in increases over conventional linear low density polyethylene in the material's tensile strength, elasticity and ductility. The carbon nanotubes constitute between about 0.08% and 1.0% by weight of the linear low density polyethylene nanocomposite fiber. Optimal toughness is found at about 0.3 wt %. The linear low density polyethylene nanocomposite fibers are made by first melting a quantity of linear low density polyethylene, and then blending a quantity of carbon nanotubes into the melted linear low density polyethylene to form a mixture, The mixture is then extruded to form the linear low density polyethylene nanocomposite fibers, which are then spun in a spinneret die to produce the finished linear low density polyethylene nanocomposite fibers.

摘要： The LLDPE-LDPE blown film blend is a blown film made from a mixture of unimodal hexene-LLDPE (also referred to as h-LLDPE) and LDPE having a blend ratio between 2%-10% of LDPE added to 98%-90% of h-LLDPE. This blend results in a TD (transverse direction) tear resistance increase by 100% for a composition of between 2%-10% of LDPE with LLDPE. Impact failure energy increases by 20% for the composition of 5% LDPE with 95% h-LLDPE. There is improvement in strength in the TD direction for the composition starting at 10% of LDPE with h-LLDPE. The toughness in the MD (machine direction) direction increases for the compositions of approximately 10% LDPE with h-LLDPE. Moreover, film production of a composition starting at approximately 10% of LDPE with LLDPE requires less energy.
摘要翻译： LLDPE-LDPE吹塑薄膜共混物是由单峰的己烯LLDPE（也称为h-LLDPE）和LDPE的混合物制成的吹塑薄膜，LDPE的混合比为2％-10％，加入到98％-90％的h-LLDPE。该混合物导致LDPE与LLDPE在2％-10％之间的组合物的TD（横向）抗撕裂性提高100％。对于具有95％h-LLDPE的5％LDPE的组合物，冲击破坏能提高20％。对于在具有h-LLDPE的LDPE的10％起始的组合物，TD方向的强度有所改善。对于具有h-LLDPE的约10％LDPE的组成，MD（纵向）方向的韧性增加。此外，从LLDPE的LDPE约10％开始的组合物的薄膜生产需要更少的能量。
