Abstract
The atmospheric pressure plasma graft polymerization treated fluorocarbon plastics and the metal are bonded, performing the adhesiveness evaluation. In this research, atmospheric NTP (nonthermal plasma) graft polymerization technique treats a surface of PTFE in dry process that can reduce environmental loading. The treated PTFE is adhered with the stainless steel plate, is performed peeling test. We examine peeling strength and consider the best condition for practical application by peeling strength. A concrete numerical target is 3 N/mm that is the standard adhesive strength of prior technique. When the graft polymerization technique is conducted, we use monomer such as acrylic acid (CH 2 =CHCOOH) and target material such as PTFE. From the experimental results, there is a tendency that as the temperature of acrylic acid increases, the peeling strength is high. When the temperature of acrylic acid is 60 °C and the Ar main flow rate is 40 L/min, the peeling strength is maximized, 1.56 N/mm. Furthermore, by analysis of XPS (X-ray photoelectron spectroscopy) and SEM (Scanning electron microscope), we evaluate the atmospheric pressure plasma graft polymerization process from a different perspective, and search optimized condition of the processing method.
