【摘要】 发展兼具防伪和溯源功能的信息化材料，以实现“一物一码”将是打击假冒伪劣商品的重要手段。本文拟对多维空间内具备特异信号的叁键拉曼散射光谱进行可控编码，构建超容量的“拉曼码”并作为新型的信息化材料用于防伪及信息加密研究。在课题组前期叁键拉曼标签制备基础上，进一步筛选和制备出六种既含乙烯基又可在聚合中保护叁键特征基团的小分子单体，随后通过乳液聚合方式制备出高灵敏、高光谱分辨、叁键拉曼散射在1 800～2 800 cm^-1区间可调谐且具备多色特性的聚合物拉曼标签；叁键拉曼标签为墨水着色剂与可光交联的水性树脂材料共混，制备出了可光固化3D打印的“拉曼墨水”,进一步利用3D打印技术实现了“拉曼墨水”在多种包装基材上多维度且特异性的图形、文字等信息打印，进而叁键聚合物标签可在打印的限域空间内进行可控排布，从而获得了一系列的多维结构码，即超级拉曼码。利用超快拉曼成像技术可对超级拉曼码（图文信息）进行解码，图文中光谱信息的差异性编码将对多类型、多样化商品的防伪及溯源有指导意义。更多还原

【Abstract】 Developing information materials with both anti-counterfeiting and traceability functions to achieve “One thing, One code” will be an important method to crack down on fake and shoddy commodities. In this paper, we constructed super Raman codes with the various triple bonded Raman scattering, which were further controlled coding under multi-dimensional space by 3D printing. Six kinds of small molecules containing vinyl and triple bond were selected from our previous synthesized, then the multicolor Raman active polymers with high sensitivity and tunable triple bonded Raman scattering within the range of 1 800～2 800 cm^-1 were synthesized through emulsion polymerization. “Raman ink” was further blended with synthesized Raman active polymers, water-based resin material and light crosslinking agents. Multidimensional and specific information from the “Raman ink” were achieved in a variety of packaging substrate by 3D printing technology, thus triple bonded polymers could be controlled in the printing of the confined space configuration. The super-fast Raman imaging technology have used to decode the super Raman code（graphic information）, and the differential coding of the spectral information in the image and text will provide guidance for the anti-counterfeiting and traceability of multi-types and diversified commodities.更多还原
