摘要
为了扩展传统油墨除书写、绘画等之外的使用功能,改善油墨环境友好性,使其适配柔性电子、绿色电子产品的生产制造及科普教学需求,通过n型有机热电材料聚苯并二呋喃二酮(PBFDO)与二甲基亚砜(DMSO)复合制备了一种n型有机热电墨水,探究了其流变特性、热电性能及多场景应用潜力。基于环保可降解理念,以纤维素基纸张及聚乙烯薄膜为柔性基底,创新开发了直写式n型PBFDO热电墨水体系。通过直写图案化技术制备了低压驱动(3~5V)的纸基发光电子玩具和温差发电装置,构建的柔性薄膜传感器可同步监测人体运动姿态与水温识别,展现出多模态信号响应特性。该技术通过“书写即制造”的理念,为柔性可穿戴电子器件、纸质电子玩具等提供了更加便捷的解决方案,推动了柔性电子器件向低碳化、普适化方向发展。
To expand the application functions of traditional inks beyond writing and painting,improve their environmental friendliness,and make them suitable for the production and manufacturing of flexible electronics and green electronic products as well as for science popularization and education needs,an n-type organic thermoelectric ink was prepared by compounding n-type organic thermoelectric material poly(benzodifurandione)(PBFDO)with dimethyl sulfoxide(DMSO).The rheological properties,thermoelectric performance and multi-scenario application potential of the ink were investigated.Based on the concept of environmental protection and biodegradability,a direct-writing n-type PBFDO thermoelectric ink system was innovatively developed using cellulose-based paper and polyethylene film as flexible substrates.Low-voltage-driven(3~5V)paper-based light-emitting electronic toys and thermoelectric generators were fabricated by direct-writing patterning technology.The constructed flexible film sensor could simultaneously monitor human motion posture and water temperature recognition,demonstrating multi-modal signal response characteristics.This technology,through the concept of“writing as manufacturing”,provided a more convenient solution for flexible wearable electronic devices and paper-based electronic toys,promoting the development of flexible electronic devices towards low-carbon and universalization.
