项目摘要

This study has initiated by collaboration with the researchers in the related fields in the department of chemistry and materials science of Polytechnic University, N Y, USA, in order to elucidate the dynamic aspects of self-organizing and self-structuring polymeric materials, in which multi-phase and hierarchic structures are the characteristics. The total plan has been grouped in to the following five categories :1. Slow dynamics of structural formation in polymer-blend organizing materials.2. Development of new block copolymers and their organization and functionalization.3.Analysis of organizing superstructures by use of dynamic light scattering method.4. Structurization of synthetic-biological complex systems and reaction analysis.5. Development of new photo-functional organizing materials.6. Molecular design of self-organizing materials.The attained results from each category were :1. Optical observation of organizing process during the phase-separation of thermoresponsive phase-separating polymericmaterials.2. Development of A-B-A type block copolymer having amphiphilic properties by using terechelic reactive oligomers.3. Structural analysis of block- and blend-based organizing materials.4. Unified understanding for structural formations in proteins and synthetic polymers.5.Development of new self-organizing polymeric materials in which structural formation is induced by light stimulation.6. Design and development of novel biodegradable polyester-based self-organizing materials.These works have been carried out with a tight exchange of research information and discussion between two Institutes and Joint-symposium was organized every year to present the details of newly attained results and to exchange productive discussion upon every result.

本研究由美国纽约理工大学化学与材料科学系相关领域的研究人员合作发起，旨在阐明以多相和分级结构为特征的自组织和自结构聚合物材料的动态方面。总计划分为以下五类： 1．聚合物共混组织材料中结构形成的缓慢动力学。2．新型嵌段共聚物的开发及其组织和功能化。3．动态光散射法分析组织超结构。4．合成生物复杂系统的结构化和反应分析。5．新型光功能组织材料的开发。6．自组织材料的分子设计。每个类别所获得的结果是： 1．热响应相分离高分子材料相分离组织过程的光学观察。2．利用端爪反应性低聚物开发具有两亲性的A-B-A型嵌段共聚物。 3．块状和混合状组织材料的结构分析。4．对蛋白质和合成聚合物结构形成的统一认识。5.开发光刺激诱导结构形成的新型自组织高分子材料。6．新型可生物降解聚酯基自组织材料的设计和开发。这些工作是在两个研究所之间密切交流研究信息和讨论的情况下进行的，每年都会组织联合研讨会，详细介绍新取得的成果，并对每项成果进行富有成效的讨论。
