A polymer surface treatment irradiated system by a XeCl excimer laser is designed. The hydrophilic character of fluorocarbon-resin with water is improved by solutions such as H2O, H3BO3(1%), and NaOH(0.5%) reacting with fluorocarbon-resin while the XeCl excimer laser is irradiating. The relationship between the contact angle of water on the surface of polymer and the laser intensity and laser pulse shots is measured. The smallest contact angle of 28° is obtained. The mechanism of these phenomena is discussed.
