| 中文摘要: |
| 自振荡高分子凝胶是一种智能化软物质材料,其体积无需外界刺激即能自发膨胀收缩,实现化学能向机械能转化,具有良好的研究和应用前景。本文介绍了自振荡凝胶的设计和振荡化学反应机理、不同尺度的自振荡行为、以及温度、浓度、化学结构和外界刺激等因素对自振荡行为的影响等内容。从凝胶自驱动运动和物质运输两方面介绍仿生驱动凝胶在组织工程、生命科学、药物缓释和材料等领域的潜在应用,并展望了自振荡凝胶未来研究趋势。 |
| 英文摘要: |
| Self-oscillating polymer gels, one of smart soft materials, have spontaneous swelling-deswelling changes without external stimuli. It has application prospect due to the transformation of chemical energy to mechanical energy. In this paper, design philosophy, reaction mechanism of self-oscillating polymer gels, and self-oscillating behaviors at different scales were reviewed. And factors such as reaction temperature, substrate concentration, chemical structure and external stimulation on self-oscillating behaviors were also analysed. Design of biomimetic soft actuators included self-driving gels and autonomous transportation actuators. The trend of research and their application as functional soft materials in tissue engineering, life science, controlled drug-release, and material were introduced. |
