摘　　要：目的在当今环保意识不断增强的背景下,纸基微流控技术以其低成本、可降解的特点,逐渐成为包装行业的研究热点。本研究旨在设计一种基于纸基微流控芯片的多功能包装,通过碳点的特异性荧光响应实现防伪功能,并结合导电油墨器件添加趣味教学功能,以满足现代环境的无废弃包装要求。方法通过丝网印刷的方法,构建荧光传感与导电油墨器件一体化的纸基微流控芯片,粘贴在传统纸质包装的内表面制备具有防伪功能的无废弃包装。结果经测试,该包装可以通过碳点材料的荧光与猝灭鉴别产品真伪,并在滴入导电油墨后通过发光器件起到趣味教学的作用。结论将纸基微流控芯片与纸质包装相结合,为产品防伪与包装可持续应用提供了一种可行的方法。In the context of the growing awareness of environmental protection today,paper-based microfluidic technology,characterized by low cost and biodegradability,has gradually become a hot topic of research in the packaging industry.The work aims to design multifunctional packaging utilizing paper-based microfluidic chip technology,which utilizes the unique fluorescent response of carbon dots for anti-counterfeiting purposes and integrates a teaching component through the use of conductive ink devices to meet the contemporary environmental standards for waste-free packaging materials.Through the utilization of silk screen printing technique,a paper-based microfluidic chip integrating fluorescent sensing and conductive ink components was fabricated,adhered onto the inner surface of conventional paper packaging to create waste-free anti-counterfeit packaging.This integration allowed for product authenticity verification under UV light irradiation and offered an educational dimension through luminescence demonstration post-application of conductive ink.The fusion of paper-based microfluidic chips with paper packaging presents a viable approach for enhancing product security and promoting sustainable packaging practices.
