摘      要：The carbon nanotubes(CNTs) and two types of low density polyethylene(LDPE, DFDA7042 and EF7B) were melting blended and blown into films with thickness 10 μm. The ultraviolet(UV) transparent characteristics and the mechanical properties of the films were investigated. The UV transparency of the films can be reduced significantly when the content of CNTs was very low: the UV transparency of the DFDA7042 film filled with 0 01% CNTs and the EF7B film filled with 0 01% CNTs was decreased by 52.1% and 50.8%, respectively compared to the blank films. CNTs would agglomerate in the LDPE matrix with the CNTs content increasing, which lead to the increase of the UV transparency.
