小行星9510272 该项目的主要目标是建立通用的原则，使有机-无机复合材料具有控制的微观结构进行设计，并建立机械路径管理的自组装复合材料形成的水溶液中的反应。 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使用，从而研究这些聚合物和基质相之间的相互作用;和（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。 吸附现象的调查和相互作用的表面具有空间和成分控制的功能团也将进行探索。 该研究项目对设计和开发形成复合材料的化学路线非常重要。 它模拟了生物复合材料的属性，这些属性与它们在净形状、低温和压力下的形成相关。 ***

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. ***
