摘要
天然高分子材料具有来源广泛、化学成分多样、生物相容性和生物降解性良好等优势,是一类绿色可持续再生资源.近年来,基于天然高分子的绿色柔性传感器件研究受到了国内外学者的广泛关注,并取得了长足的进展.本文以天然高分子导电材料为主线,总结了基于天然高分子制备导电材料的模板法和掺杂法.模板法直接以天然高分子材料的天然骨架结构作为基质,而掺杂法以天然高分子材料处理后的产物或衍生物作为基质.归纳了基于天然高分子的柔性导电材料在湿度、温度、应变、气流/气体、光、生物传感器件中应用的研究进展,最后展望了基于天然高分子的柔性导电材料在设计和组装柔性传感器方面的前景,为高效发展绿色柔性电子和天然高分子材料的高值化利用提供新思路.
Natural polymers are environmentally friendly and sustainable renewable raw materials with many advantages, such as variety of sources, different chemical components, excellent biocompatibility and biodegradability. The controllable production of conductive materials derived from natural polymers with excellent properties is critical for the design and manufacture of new conductive materials, and the assembly of unique functional flexible sensors. Recently, the research of green flexible sensors based on natural polymers has been widely concerned by scientists at home and abroad, and great progress has been made. The review summarizes the preparation approaches of conductive materials based on natural polymers, which can be divided into template method and doping method. The template method takes the micro-nano skeleton structures of the natural polymers as matrix, while the doping method takes the products or derivatives of the natural polymers as matrix. The research progresses of flexible sensors based on natural polymers are summarized, including the flexible sensors of humidity, temperature, strain, airflow, gas, light and biomedicine. Finally, the prospects of flexible conductive materials based on natural polymers in the design and assembly of flexible sensors are prospected, and novel ideas to efficient utilization of natural polymer materials for developing green flexible electronics have been proposed.
