Ion Permeation in Polyethylene and Ethylene-based Copolymers

폴리에틸렌과 에틸렌계 공중합체에서의 이온투과 현상

Ion permeation in polyethylene and ethyene-based copolymers has been investigat-ed Ions permeate faster through non-crosslink-ed films than through crosslinked films. which can be attributed to the decreased chain flexibility and free volume by crosslinking reaction, In EVA/EAA and EVA/ionomer blends, diffusion coefficients of ion decrease with the increase of EAA and ionomer content This was attributed to the increas of acid group acting as ion trapping site in the blends
