Liquid metal (LM)-based nano-inks are facing challenges for their use in wearable electronics due to their low colloidal/chemical stability, cost, potential hazards, and the lack of multifunction. Here, we demonstrate a dialdehyde xylan (DAX) stabilizing LM ink encompassing low-cost, long-term stability, biocompatibility, and catalytic activity. DAX with a high molecular weight was obtained by converting the industrial pulping byproducts, xylan, in water directly with sodium periodate (NaIO₄) at room temperature. The DAX/LM ink revealed remarkable chemical and colloidal stability for a period of approximately 7 d, as well as high affinity to various substrates. Compared with other LM nano-inks, the DAX/LM ink showed a remarkable catalytic feature for ultrafast polymerization of vinyl monomers, as well as chemical reactivity to construct double network (DN) gels with motion-sensing properties. This work holds promises for the high value-added utilization of lignocellulosic biomass in the fields of future flexible electronic materials.

基于二醛木聚糖的可持续、稳定和催化液态金属纳米油墨

基于液态金属 (LM) 的纳米墨水由于其胶体/化学稳定性低、成本、潜在危害和缺乏多功能性，在可穿戴电子产品中的使用正面临挑战。在这里，我们展示了一种二醛木聚糖 (DAX) 稳定 LM 墨水，包括低成本、长期稳定性、生物相容性和催化活性。通过将工业制浆副产物木聚糖直接与高碘酸钠 (NaIO ₄）在室温下。DAX/LM 墨水在大约 7 天的时间内显示出显着的化学和胶体稳定性，以及对各种基材的高亲和力。与其他 LM 纳米墨水相比，DAX/LM 墨水对乙烯基单体的超快速聚合表现出显着的催化特性，以及构建具有运动传感特性的双网络 (DN) 凝胶的化学反应性。这项工作有望在未来柔性电子材料领域实现木质纤维素生物质的高附加值利用。
