摘要
传统水凝胶存在机械性能和可加工性差的缺点,本研究制备了芳纶增强MXene-聚丙烯酸-无定型碳酸钙(ANF/MXene-PAA-ACC)复合水凝胶,并研究了其相关力学与物理性能.首先,通过氟化锂和盐酸刻蚀法,结合超声剥离工艺制备了二维MXene单层纳米片,将其应用到PAA-ACC复合水凝胶中.为了提高MXene-PAA-ACC的力学性能,进一步通过加入芳纶,制备了 ANF/MXene-PAA-ACC复合水凝胶.采用扫描电镜和万能力学试验机对复合水凝胶的表观形貌、力学性能、自修复和粘附性等物理性能进行了表征和测试.结果表明:与PAA-ACC水凝胶相比,ANF/MXene-PAA-ACC水凝胶的可加工性、力学性能、粘附性、自修复性都得到了提高.
Abstract
Traditional hydrogels have the disadvantages of poor mechanical properties and machinability.In this study,aryl-reinforced MXene-poly(acrylic acid)-amorphous calcium carbonate(ANF/MXene-PAA-ACC)composite hydrogels were prepared,and the related mechanical and physical properties were studied.Firstly,two-dimensional MXene monolayer nanosheets were prepared by the method of lithium fluoride and hydrochloric acid etching combing with ultrasonic stripping process.Then,it was added into PAA-ACC composite hydrogel.In order to improve the mechanical properties of MXene-PAA-ACC hydrogel,ANF/MXene-PAA-ACC composite hydrogel was prepared by adding aryl fiber.The appearance,mechanical properties,self-healing and adhesion properties of the ANF/MXene-PAA-ACC composite hydrogels were characterized and tested by scanning electron microscopy and universal mechanical testing machine.The results showed that compared with PAA-ACC hydrogels,the machinability,mechanical properties,adhesion and self-repair performance of ANF/MXene-PAA-ACC hydrogels were all improved.
