Ni、Fe、Ti、Al、Au 和 Cu 分别蒸发并沉积到聚乙烯和聚四氟乙烯 (PTFE) 薄膜的两侧。比较了不同金属-聚合物-金属复合材料的粘合接头强度，并研究了金属化引起的后续表面改性。研究表明，在聚乙烯或聚四氟乙烯的表面沉积金属层并随后去除后，其润湿性没有变化。也没有表面氧化或不饱和的证据。聚乙烯的凝胶分数显示出不同金属-聚合物复合材料表面的接头强度和交联之间存在明确的相关性。与聚乙烯形成最强接头的金属产生最大量的交联。相反，形成最弱接头的金属导致交联量最少。
Ni, Fe, Ti, Al, Au, and Cu were each evaporated and deposited onto both sides of polyethylene and poly(tetrafluoroethylene) (PTFE) films. Adhesive joint strengths of the different metal–polymer–metal composites were compared and subsequent surface modifications due to metalization were investigated. Studies show no change in wettability of polyethylene or PTFE after a metal layer was deposited onto their surfaces and subsequently removed. There was also no evidence of oxidation or unsaturation of the surface. Gel fractions of polyethylene show a definite correlation between joint strength and crosslink at the surfaces of the different metal–polymer composites. Metals forming the strongest joints with polyethylene yield the greatest amount of crosslinking. Conversely, metals forming the weakest joints result in the least amount of crosslinking.
