9510272布朗这个项目的主要目标是建立通用原则，允许设计具有受控微结构的有机-无机复合材料，并建立控制水溶液中反应形成的复合材料的自组装的机械路径。将追求三个技术目标：(1)集中于建立无机基质相的化学、其形成的动力学和伴随的微结构发展之间的关系；(2)探索具有特定聚合物构象和官能团的聚合物的使用，从而研究这些聚合物与基质相之间的相互作用；以及(3)建立聚合物结构和基质相前体的水解对聚合物交联物形成的影响。还将探索吸附现象以及与具有空间和组成可控官能团的表面的相互作用。这个研究项目对于设计和开发形成复合材料的化学路线是很重要的。它模拟了生物复合材料在净形状、低温和压力下形成的属性。***

9510272 Brown The primary goals of this project are to establish the generic principles which allow organic-inorganic composites having controlled microstructures to be designed and to establish mechanistic paths governing self-assembly of composites formed by reaction in aqueous solutions. Three technical objectives will be pursued: (1) to concentrate on establishing the relationships between the chemistry of the inorganic matrix phase, the kinetics of its formation, and the attendant microstructural development; (2) to explore the use of polymers having specific polymer conformations and functional groups and thereby to investigate the interaction between these polymers and the matrix phases; and (3) establish effects of the polymeric structures and the hydrolysis of the matrix phase precursors on the formation of polymer crosslinks. The investigation of adsorption phenomenon and interaction with surfaces having spatially and compositional controlled functional groups will also be explored. %%% This research project is important to the design and development of chemical routes to form composites. It emulates the attributes of biological composite materials associated with their formation at net shape, low temperature and pressure. ***
