项目摘要

Recently, there is much interest in nanocomposite materials consisting of noble metal nanoparticles dispersed in a polymer matrix due to their novel optical functional properties observed at the surface or particle plasmon resonances as a result of dielectric and quantum confinement effects during interactions with light. The Chair for Muticomponent Materials at the University of Kiel has a long standing expertise in the field of metal-polymer interfaces and composites. The present research project is concerned with producing polymer-based metal containing optical nanocomposites for functionale applications. Emphasis will be put on the preparation of nanocomposite films as well as multilyered structures of multicomponent nanocomposites and on clarifying the underlying mechanisms. In particular, we will strive for approaches that allow formation of optical nanocomposites of well defined compositions covering upto percolation composites. Two solvent free central methods of vapor phase codeposition and rf co-sputtering will be investigated in parallel for simultaneous deposition of metal and polymer. These complimentary codeposition techniques are expected to lead to develope optical nanocomposite materials with the desired and optimized compositions and to establish new facts by simulatenous studies with the two production methods. Preparatory studies already carried out in this direction have demonstrated the feasibility of the above approaches. Finally, physical properties and aging of the resulting nanocomposites will also be investigated.

最近，有很多兴趣在纳米复合材料组成的贵金属纳米粒子分散在聚合物基体中，由于其新颖的光学功能特性观察到的表面或粒子等离子体共振作为结果的介电和量子限制效应在与光的相互作用。基尔大学的多组分材料讲座在金属-聚合物界面和复合材料领域拥有长期的专业知识。本研究计划是关于生产聚合物基含金属的光学纳米复合材料的功能应用。重点将放在纳米复合薄膜的制备以及多组分纳米复合材料的多层结构和阐明潜在的机制。特别是，我们将努力的方法，允许形成光学纳米复合材料的定义明确的组成覆盖到渗滤复合材料。两种无溶剂的中心方法气相共沉积和射频共溅射将同时研究金属和聚合物的沉积。这些互补的共沉积技术，预计将导致开发的光学纳米复合材料与所需的和优化的组成，并建立新的事实，通过同时研究与两种生产方法。已经在这方面进行的筹备性研究表明了上述办法的可行性。最后，还将研究所得纳米复合材料的物理性能和老化。
