Abstract
Polyethylene terephthalate (PET) has been modified by Ti, Ni and W depositi on using a metal vapor vacuum are (MEVVA) source and implantation. The surf ace resistance of deposited PET could decrease to several hundred ohms. The adhesion of metal coating on polymers is very strong. The thickness of the deposited metal coating could be controlled from tens of nanometers to 1 m um The hardness for thick Ti and W deposited PET is 3.81 and 2.54 GPa, whic h are several times greater than that of PET. The elastic modulus of deposi ted PET increases also. Similar results have been observed for other metal implanted PET. The thickness and atomic distribution of deposited metal coa ting was analyzed using RES. The surface structure has varied after deposit ion and implantation. It is believed that the change would cause the improv ement of the conductive properties and wear resistance. (C) 2000 Elsevier S cience B.V. All rights reserved.
