| 제목 | Adhesion improvement of the silane modified poly(amic acid) to the stainless steel by atmospheric plasma treatment |
| 초록 | Abstract Poly(amic acid) and silane adhesion promoter are synthesized in order to bind plasma modified stainless steel plates. A mixture of the poly(amic acid) and vinyl imidazole modified silane is used as a new kind of adhesive and the binding sample can endure the high temperature even to 400℃ The plasma is utilized to improve the adhesion strength. Due to the water contact angle measurement and the calculation of the surface free energy, it is proved that plasma modification can change the hydrophilic property of the stainless steel plate and the adhesion strength between the poly(amic acid) and stainless steel substrate is dramatically improved. During the binding process, the curing temperature has been proved to be an important factor to influence the binding strength, and the adhesion strength is measured by the lap shear test. The water contact angle on the stainless steel substrate is measured at different plasma treatment conditions and the influence of treating time, power, and aging time after plasma treatment are discussed respectively. The surface free energy can be calculated by using the Owens-Wendt (OW) method after the water contact angle of the substrate is confirmed. The FT-IR, AFM, SEM and XPS are used to exam the plasma treated sample and the failure interface of the binding sample after the lap shear test, and the component, surface morphology and binding energies of the stainless steel substrate are analyzed. |
