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. ***

9510272 Brown 该项目的主要目标是建立通用原则，允许设计具有受控微观结构的有机-无机复合材料，并建立控制水溶液中反应形成的复合材料自组装的机械路径。 我们将追求三个技术目标：（1）集中精力建立无机基体相的化学性质、其形成动力学以及随之而来的微观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用途，从而研究这些聚合物与基体相之间的相互作用； (3)确定聚合物结构和基质相前体的水解对聚合物交联形成的影响。 还将探索吸附现象以及与具有空间和组成控制官能团的表面相互作用的研究。 %%% 该研究项目对于设计和开发形成复合材料的化学路线非常重要。 它模拟生物复合材料在净形状、低温和压力下形成的属性。 ***
