Reduction of Contraction Coefficient of Acrylic Yarn by PFP Plasma Polymerization

Plasma polymerization of Perfluoropropene(PFP) was carried out in a tubular type reactor. The Plasma was generated by coupling inductively under the fixed discharge power of 25W and the pressure of 100, 140, and 200 mTorr of radio frequency generator. PFP plasma polymerization thin films were deposited in acrylic yams. For 1 hours, the acrylic yams treated and untreated by PFP plasma were immersed in boiling water. Then the reduction of contraction coefficient of acrylic yams were measured respectively. As a result of this experiment, untreated acrylic yams were reduced around 23%, while treated yams were contracted about 18-2%.
