Aim To study the LDPE surface heparinization with plasma initiation technique, and antithrombogenicity and tissue compatibility of heparinizing LDPE surface.

The antithrombogenicity was determined by clotting time measurement in vitro and platelet adhesion experiment. It is shown that the antithrombogenicity of modified PVC materials is increased greatly.
This paper is related to surface modification of PE films by combining plasma pretreatment with UV-induced graft polymerization, in order to improve the antithrombogenicity of polyethylene (PE) films.
