The goal of this effort is to relate the composition of acetylene plasmas to processing variables used in depositing plasma-polymerized acetylene films. These films are then investigated as adhesives for rubber-to-metal bonding. Plasma composition is also correlated with such film properties as adhesion, durability of adhesion, and corrosion inhibition. Plasma-polymerized acetylene films are deposited onto steel substrates in a microwave reactor using argon or other inert gases as carrier gases. The composition and morphology of the films are controlled through external variables such as power, pressure, monomer flow rate, and RF bias of the substrate. Plasma composition is determined by residual gas analysis (RGA), optical emission spectroscopy (OES), and time-of-flight mass spectroscopy (TOFMS). Films are characterized using reflection-absorption infrared spectroscopy (RAIR), X-ray photoelectron spectroscopy (XPS), variable-angle spectroscopic ellipsometry (VASE), and atomic force microscopy (AFM). Film properties are determined with electrochemical impedance spectroscopy (EIS), fracture mechanics tests, and industrial test methods.This is a collaboration involving the University of Dayton (plasma characterization), the University of Cincinnati (plasma polymerization and film characterization), the Goodyear Tire and Rubber Company (film properties), and the Autonomous National University of Mexico (corrosion inhibition).

这项工作的目标是与乙炔等离子体的组合物，用于沉积等离子体聚合乙炔膜的处理变量。 这些薄膜，然后研究作为粘合剂的橡胶-金属粘接。 等离子体组成也与诸如粘附性、粘附耐久性和腐蚀抑制性的膜性质相关。 在微波反应器中，使用氩气或其他惰性气体作为载气，在钢基底上沉积等离子体聚合乙炔膜。 通过外部变量，如功率，压力，单体流速，和RF偏压的基板的膜的组成和形态进行控制。 等离子体成分通过残余气体分析（RGA）、光学发射光谱（OES）和飞行时间质谱（TOFMS）确定。 薄膜的特征在于使用反射吸收红外光谱（RAIR），X射线光电子能谱（XPS），可变角光谱椭圆偏振仪（VASE），和原子力显微镜（AFM）。 薄膜性能的测定采用电化学阻抗谱（EIS）、断裂力学测试和工业测试方法。这是一项合作项目，涉及代顿大学（等离子体表征）、辛辛那提大学（等离子体聚合和薄膜表征）、固特异轮胎橡胶公司（薄膜性能）和墨西哥国立自治大学（腐蚀抑制）。
