研究了热处理和物理化学处理对沉积在聚对二甲苯(PA-C)基片上的金(Au)的再结晶和附着力的改善。对An在PA-C上进行了退火处理，观察了100~250℃热处理对组织的增强作用。从Au(111)的峰强度和半峰宽来看，其结晶度随退火温度的升高而提高，这为表面提供了合适的单分子膜的形成。采用了氧等离子体、大气压等离子体、离子束、牛血清白蛋白等多种表面改性的物理和化学方法来分析表面能和粘附力。这些结果表现出优异的粘接性能，利用氧等离子体和离子束处理，通过机械互锁产生羰基。
Improvement of recrystallization and adhesion of gold (Au) deposited on parylene-c (Pa-c) substrate with heat treatment and surface modification using physical and chemical treatment was investigated. Annealing of An on Pa-c was performed to observe microstructure enhancement due to heat treatment from 100 to 250 degreesC. From the peak intensity and full-width at half-maximum of Au(111), its crystallinity appeared to improve as the annealing temperature increased, which can provide the surface with proper creation of monolayers. Several physical and chemical methods of surface modifications were employed to analyze surface energy and adhesion promotion, such as oxygen plasma, atmospheric plasma, ion beam, and Bovine serum albumin. These results exhibit excellent adhesion properties by exploiting oxygen plasma and ion-beam treatment, which induce carbonyl groups via the mechanical interlocking.
