基于石墨烯/丝素蛋白涂层的光热/压电双功能棉织物的制备及性能
Preparation and performance of photothermal/piezoelectric dual-functional cotton fabric based on graphene/silk fibroin coating
【摘要】 开发了一种基于磷酸预分散石墨烯和丝素蛋白协同作用的石墨烯/丝素蛋白复合印花浆料,通过丝网印花技术在棉织物表面构建了具有光热-压电双功能特性的智能纺织品。采用光学显微镜、扫描电子显微镜和傅里叶红外光谱等表征手段证实:石墨烯在磷酸-丝素蛋白基质中分散均匀,纤维表面形成致密连续涂层,且石墨烯诱导丝素蛋白形成β-折叠结构,显著提升材料稳定性。当石墨烯质量分数为0.9%时,织物在AM 1.5G标准光照(100 mW/cm~2)下可迅速升温至94.2℃(原棉织物约45℃);在20 N周期压力下产生约200 mV开路压电电压。该研究为开发可穿戴能量收集与热管理一体化器件提供了新的解决方案。
【Abstract】 A graphene/silk protein composite printing paste based on the synergistic action of phosphoric acid pre-dispersed graphene and silk protein is developed, and smart textiles with dual photothermal and piezoelectric properties on the surface of cotton fabrics are constructed using screen printing technology. Characterization methods such as optical microscopy, scanning electron microscopy, and Fourier transform infrared spectroscopy confirm that graphene is uniformly dispersed in the phosphoric acid-silk protein matrix, forming a dense continuous coating on the fiber surface, and that graphene induces silk protein to form a β-sheet structure, significantly enhancing the material’s stability. When the graphene mass fraction is 0.9%, the fabric can rapidly heat up to 94.2 ℃ under AM 1.5G standard illumination(100 mW/cm2)(compared to about 45 ℃ for the original cotton fabric); under a cyclic pressure of 20 N, it generates approximately 200 mV open-circuit piezoelectric voltage. This research provides a new solution for the development of integrated wearable energy harvesting and thermal management devices.
