Abstract

In our experiment, a PTFE was sputter-coated on substrates to induce water-repellent properties and the RF-magnetron sputtering method for fabrication of PTFE film is used due to the advantages of the simple process, time saving, environmentally friendly, insulating property, and a good adhesion property to substrates. As a result of the correlation between surface roughness of PTFE films and contact angle with water, we found that the roughness surfaces are proportioned to contact angles related to low interfacial energy.
