项目摘要

The proposed research is to develop new materials using supramolecular chemistry, where building blocks are organized into complex structures that endow them with remarkable properties. This concept of building hierarchical structures mimics Nature's approach to making remarkable materials, such as bone and shells. In the proposed research, hierarchical materials will be constructed predominantly using cellulose nanocrystals (CNCs) and graphene oxide (GO), nanomaterials that are thinner than 1/10,000th the width of a human hair. More specifically, CNCs and GO will be assembled inside of elastic materials to make photonic structures that respond with colour changes to changes in pressure and stress. In another approach, cellulose nanocrystals will be organized into highly porous structures that can be used to contain oil from oil spills at sea. Finally, development of molecular analogues that mimic the structure and properties of cellulose nanocrystals will provide valuable insight into these remarkable nanomaterials. The target materials are completely new and will be investigated using state-of-the-art techniques such as electron microscopy and solid-state nuclear magnetic resonance (NMR) spectroscopy. The proposed research is important for developing new materials from renewable resources, and could lead to new applications in pressure sensing, robotics, and oil clean-up.

拟议的研究是使用超分子化学的新材料开发新材料，在该化学中，构建块被组织成复杂的结构，从而赋予它们具有显着特性的复杂结构。这种构建分层结构的概念模仿了自然制造出色材料的方法，例如骨骼和壳。在拟议的研究中，将主要使用纤维素纳米晶体（CNC）和氧化石墨烯（GO）来构建分层材料，纳米材料比人毛的宽度较薄的纳米材料。更具体地说，CNC和GO将在弹性材料的内部组装，以制造光子结构，这些结构会随着压力和压力变化的颜色变化而响应。在另一种方法中，纤维素纳米晶体将被组织成高度多孔的结构，可用于在海上溢出油中的油。最后，模仿纤维素纳米晶体的结构和特性的分子类似物的发展将为这些显着的纳米材料提供宝贵的见解。目标材料是全新的，将使用最新技术（例如电子显微镜和固态核磁共振（NMR）光谱）进行研究。拟议的研究对于从可再生资源开发新材料很重要，并可能导致压力感应，机器人技术和石油清理方面的新应用。
