3 .A method for manufacturing 3-layer film inculding carbon nanotube

摘要

The present invention relates to a process for producing a polyethylene triple layer composite film containing carbon nanotubes. Accordingly, the technical idea of the present invention is to apply a protective film for IT devices such as Carbon Nano Tube (CNT), Linear Low Density Polyethylene (LLDPE) to a low density polyethylene (LDPE) ) And high density polyethylene (HDPE) in the inner layer, outer layer and middle layer, and more specifically, to a composite film having a three-layer structure of inner layer, outer layer and middle layer, CNT is used as a conductive filler in order to prevent contamination of the adherend due to migration phenomenon. LDPE / LLDPE is used in the intermediate layer so as to reduce cost and workability of the composite material. In the outer layer, To prevent the curl phenomenon due to the difference in viscoelastic characteristics between the carbon nanotubes and the HDPE, To provide it with a purpose.
