Pd nanoparticles were immobilized on an acrylonitrile-butadiene-styrene copolymer (ABS) substrate using ionizing radiation. The samples were prepared by irradiating plastic zipper packs containing ABS substrates and a Pd(NO) aqueous solution with a high-energy electron beam (4.8 MeV). Pd nanoparticles immobilized on the ABS substrate surfaces were observed using scanning electron microscopy (SEM). The chemical state of Pd was found to be coordinated to a carbonyl group or a metallic state by X-ray photoelectron spectroscopy (XPS) measurements. The peel strength of the Cu film on the Pd/ABS samples was 0.7 N/mm or higher. This result shows that the prepared Pd/ABS samples have high adhesion strength, despite not undergoing treatments such as etching with chromic acid. This method is expected to immobilize metal nanoparticles, not only on plastic plates but also on various other materials.
使用电离辐射将钯纳米颗粒固定在丙烯腈-丁二烯-苯乙烯共聚物（ABS）基底上。通过用高能电子束（4.8 MeV）辐照含有ABS基底和硝酸钯水溶液的塑料拉链包装来制备样品。使用扫描电子显微镜（SEM）观察固定在ABS基底表面的钯纳米颗粒。通过X射线光电子能谱（XPS）测量发现钯的化学状态与羰基配位或呈金属态。钯/ABS样品上铜膜的剥离强度为0.7 N/mm或更高。该结果表明，所制备的钯/ABS样品具有高粘附强度，尽管未经过诸如用铬酸蚀刻等处理。预计该方法不仅可以将金属纳米颗粒固定在塑料板上，还可以固定在各种其他材料上。
