Polyvinyl alcohol is unique among polymers. Apart from its preparation, it is not built up in polymerization reactions from monomers, unlike most vinyl-polymers, and it is biodegradable in the presence of suitably acclimated microorganisms. It is an environmentally friendly material for a wide range of applications, from medical ones, based on its biocompatibility, to integrated optics. This paper reviews, in addition to the preparation and optimization of films of polyvinyl alcohol doped with different metal species, the role of dopants and doping technologies in the involved electronic mechanism. The optical properties were studied by UV-VIS-IR, Mössbauer spectroscopy, and other measurement techniques, with applications such as real-time holography, microlasers, optical sensors or nanophotonics in mind.
聚乙烯醇在聚合物中是独一无二的。与大多数乙烯基聚合物不同，除了其制备之外，它不会在聚合反应中从单体中构建，而且在适当驯化的微生物存在下可生物降解。它是一种环保材料，可用于广泛的应用，从基于其生物相容性的医学应用到集成光学。除了制备和优化掺杂不同金属物种的聚乙烯醇薄膜外，本文还综述了掺杂剂和掺杂技术在涉及的电子机制中的作用。通过 UV-VIS-IR、穆斯堡尔光谱和其他测量技术研究了光学性质，并考虑了实时全息术、微激光器、光学传感器或纳米光子学等应用。
