随着全球对能源需求的上升, 能源短缺是世界各国面临的重大难题, 因此新能源开发是缓解该问题的重要途径。洁净型新能源的开发，不但可以解决能源短缺, 而且可以有效地避免能源转化导致的环境污染问题。本项目以空气湿气为洁净能源开发对象, 对湿气敏感的琼脂糖薄膜化学结构修饰与机械性能表征, 及能量转化机理进行深入研究。以湿气驱动薄膜的可逆变形机理为研究重点,为琼脂糖薄膜更高效的能量转化提供理论依据和设计思路。本项目旨在引导新能源开发模式, 拓展洁净型能源开发途径，为新能源开发与利用奠定理论基础和技术参考。

With rising demand for energy, energy shortage is a major problem in the world, thus development of new energy source is of significance to alleviate the problem, which is not only capable of solving the shortage of energy, but also can effectively avoid environmental pollution caused by energy conversion. In this project, we will exploit new energy from moist air by means of agarose-based humidity-responsive actuator that is capable to convert humidity to mechanical energy，and will also deeply investigate on the structural features of agarose and modify it via chemical protocols to enhance its mechanical performance. We hope to provide the theoretical basis and design ideas for preparation of smart materials that are applied for more efficient energy conversion in the future. The project aims to provide theoretical foundation and technical reference for exploitation and utilization of new energy.
