TECHNICAL SUMMARY:Driven by both the scientific curiosity and the technical importance of soft layered materials such as graphene oxide (GO) a single atomic layered, oxygenated carbon sheet, this CAREER proposal, co-funded by the Solid State and Materials Chemistry (SSMC)/Division of Materials Research (DMR) and Chemical Measurement and Imaging (CMI)/Chemistry (CHE) programs aims to explore the soft material characteristics of GO-based materials with a focus on their assembly behaviors. GO can be viewed as an unconventional type of soft material possessing characteristics of polymer, colloid, membrane and amphiphile. Assembly should be a critical component in the structure-property relationship of such materials. Studying their interaction and assembly can reveal interesting fundamental material behaviors and help to design better synthesis and processing strategies. The overall goals of this proposal are to advance the fundamental understanding of this unconventional type of soft material, develop new structural modification methodologies, design advantageous material processing strategies, invent new characterization techniques, and create new functional material systems by controlled assembly of the single sheets.NON-TECHNICAL SUMMARY: If successful, discoveries from this proposal could lead to new materials and technologies for electronics, cleaner energy and better environment, all are central to the national interest. To maximize and expedite the societal impact, the PI will establish partnership with small businesses to transfer discoveries to industry. Results will be broadly disseminated, especially to teachers of younger students through educational journals, and to the general public using the Web2.0 communication and information sharing techniques. By integrating science and art or popular culture, research results will be interpreted in formats understandable and useful for nonscientists. Participation of underrepresented minority groups in research will be motivated through the success of the PI's current minority students, and will be broadened beyond Northwestern through the Summer Research Opportunity Program (SROP). New courses in the areas of soft materials and chemistry will be developed to enrich the department's curricula.

技术摘要：受科学好奇心和软分层材料（如氧化石墨烯（GO））的技术重要性的驱动，单原子分层，含氧碳片，由固态和材料化学（SSMC）/材料研究部（DMR）和化学测量和成像（CMI）/化学（CHE）计划共同资助的CAREER提案旨在探索GO基材料的软材料特性，重点是它们的组装行为。GO是一种非常规的软质材料，具有聚合物、胶体、膜和两亲物的特性。组装应该是这种材料的结构-性质关系中的关键组成部分。研究它们的相互作用和组装可以揭示有趣的基本材料行为，并有助于设计更好的合成和加工策略。该提案的总体目标是推进对这种非常规类型的软材料的基本理解，开发新的结构改性方法，设计有利的材料加工策略，发明新的表征技术，并通过控制单片的组装来创建新的功能材料系统。如果成功的话，这项提案的发现可能会导致电子产品的新材料和技术，更清洁的能源和更好的环境，所有这些都是国家利益的核心。为了最大限度地扩大和加快社会影响，PI将与小企业建立伙伴关系，将发现转移到工业中。研究结果将广泛传播，特别是通过教育期刊向年轻学生的教师传播，并利用Web2.0通信和信息共享技术向公众传播。通过将科学与艺术或流行文化相结合，研究结果将以非科学家可以理解和有用的形式进行解释。参与研究的代表性不足的少数群体将通过PI的当前少数民族学生的成功激励，并将通过夏季研究机会计划（SROP）扩大到西北以外。将开发软材料和化学领域的新课程，以丰富该部门的课程。
