In this present work, we are reporting a novel approach for fabrication of a kind of highly absorbent, highly stable, flexible, and compact biopolymeric hydrogel bound cotton patch. This novel technique not only exempts the spinning of cotton yarn and use of loom or other kinds of weaving machines but also makes it possible to get a soft but mechanically robust textile material. The mechanical strength and softness as well as the flexibility of such patches can be tuned just by varying the concentration of the biopolymer. Incorporation of graphene oxide in such patches not only improved the mechanical strength but also added the antimicrobial property to the patches. These patches are even stable in the presence of aqueous medium. Most importantly the polymeric matrix hydrogel part, present over the surface of cotton fibers, creates the possibility of loading different kinds of drugs, micro- or nanomaterials, different chemicals, etc. for numerous applications. With this hydrogel coated cotton patch we finally came out with a bandage material – a complete package with a minimal number of ingredients, viz., graphene oxide and curcumin, specially designed to work on infected wounds.

无需编织即可制造紧凑棉布贴片的方法：一种智能绷带材料

在本工作中，我们报告了一种新颖的方法，用于制造一种高吸收性，高稳定性，柔性和致密性的生物聚合物水凝胶结合棉片。这种新颖的技术不仅免除了棉纱的纺丝和织机或其他类型织机的使用，而且使获得柔软但机械强度高的纺织材料成为可能。仅通过改变生物聚合物的浓度就可以调节此类贴剂的机械强度和柔软性以及柔韧性。在这样的贴剂中掺入氧化石墨烯不仅改善了机械强度，而且还为贴剂增加了抗菌性能。这些贴剂甚至在水性介质存在下也是稳定的。最重要的是，存在于棉纤维表面的聚合物基质水凝胶部分 为多种应用提供了装载不同种类的药物，微米或纳米材料，不同化学药品等的可能性。有了这种水凝胶涂层的棉布，我们终于推出了绷带材料-完整的包装，其中包含最少数量的成分，即氧化石墨烯和姜黄素，专门设计用于感染的伤口。
