▎ 摘  要

NOVELTY - Use of carbon nanofillers comprising carbon nanotubes, carbon nanofibers and/or graphene to improve UV stability of a composite material comprising a polymer composition, is claimed. The carbon nanofillers are present in amount of 0.1 ppm to 0.25 wt.%, preferably 1 ppm to 0.1 wt.% relative to the composite material. USE - The carbon nanofiller is useful for improving UV stability of a composite material, which is useful for manufacturing composite products such as wires, films, tubes, fibers and nonwoven fabrics such as felts, for conduits of optical fibers, cable sheathing, gas conduits or water discharges and industrial extruded or molded coatings, for manufacturing articles by injection molding, extrusion or compression molding or in an automotive industry or for protection of agricultural land such as soil and shake lands, where the film is a UV, visible or infra red light transmission film having a thickness of 10-50 mu m and comprises 5% of absorbent (all claimed). ADVANTAGE - The carbon nanofiller improves aging resistance and UV stability of the composite material, and has improved dispersibility and high electrical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of a stabilized composite material for the manufacture of composite products such as wires, films, tubes, fibers and nonwoven fabrics such as felts, for conduits of optical fibers, cable sheathing, gas conduits or water discharges and industrial extruded or molded coatings, for manufacturing articles by injection molding, extrusion or compression molding, in an automotive industry or for protection of agricultural land such as soil and shake lands.
