摘　　要：皮革具有良好的物理机械性能、生物相容性和可生物降解性等优势,在可穿戴电子领域受到广泛关注.然而,摩擦电极性弱以及在炎热天气下长期佩戴时的热舒适性差严重限制了高性能摩擦电传感皮革的发展.基于此,本研究设计合成了一种含氟笼型倍半硅氧烷复合材料(FPOSS)对皮胶原纤维改性,利用FPOSS上的-F基团增强皮革的吸电子能力,提高其摩擦电传感性能;利用FPOSS中丰富的Si-O-Si键在长波红外区域(8~13μm)较高的红外发射率,赋予皮革辐射冷却性能,制备了一种热舒适摩擦电传感皮革.结果表明,该皮革具有极高的灵敏度(1.88 V/k Pa)和良好的稳定性,经过8500次的循环测试其性能基本维持稳定.此外,可实现10℃的日间辐射降温,以满足在炎热环境下人体皮肤的热舒适度.本研究为可穿戴热舒适自供电电子产品的设计开发提供了新的思路,为推动皮革行业高值化发展提供了新途径.Leather has the advantages of good physical and mechanical properties,biocompatibility and biodegradability,and has been widely concerned in the field of wearable electronics.However,weak triboelectric polarity and poor thermal comfort when worn for long periods in hot weather have severely limited the development of high-performance triboelectric sensing leather.Herein,a fluoro-polyhedral oligomeric silsesquioxane composite material(FPOSS)was designed and synthesized to modify leather collagen fiber.The-F group on FPOSS was used to enhance the electron absorption ability of leather and improve the triboelectric self-energy sensing performance of leather.In addition,the high infrared emissivity of the rich Si-O-Si bond in FPOSS in the long-wave infrared region(8-13μm)gives the leather radiative cooling properties,and a kind of thermal comfort triboelectric sensing leather is prepared.The results show that the leather has extremely high sensitivity(1.88V/kPa)and good stability,and its performance is basically stable after 8500 cycles of testing.In addition,daytime radiation cooling of 10℃ can be achieved to meet the thermal comfort of human skin in hot environments.This study provides a new idea for the design and development of wearable thermal comfort self-powered electronic products,and provides a new way to promote the development of high value leather industry.
