Method for manufacturing an aramid paper with an applied plasma treatment |
摘要 |
An aramid paper made from aramid fibrid and short fiber and formed into a paper shape has two sides and a surface and includes a thermal bonding face located in at least one of the sides of the aramid paper, the thermal bonding face having such a property as to be directly thermally bondable with another sheet of aramid paper of the same material or a polyester film at a thermal bonding temperature ranging from 90° C. to 200° C. when a plasma treatment is applied to the surface of the aramid paper. The plasma treatment has an intensity ranging from 30 W·min/m2 to 1500 W·min/m2, and the thermal bonding face has a composition ratio (O/C) of the number of oxygen atoms (O) to the number of carbon atoms (C) ranging between 150% and 230% of a theoretical value of an atom number ratio.
