竹纤维素基黏附材料的制备及其湿组织黏附性能研究
Study on the Fabrication of Bamboo Cellulose-based Adhesive Materials and Its Wet Tissue Adhesion Property
摘要
Abstract
To achieve high-value applications of bamboo,and to address the poor wet adhesion performance of current cellulose-based tissue adhesives,carboxymethyl cellulose(CMC)was prepared from bamboo cellulose fibers in this study.Through methacrylate esterification mod-ification,a photo-crosslinkable carboxymethyl cellulose methacrylate(CMC-MA)was synthesized,then it was copolymerized with acrylic acid(AA)and the catechol-containing monomer dopa(DMA)under blue light to construct a bamboo cellulose-based adhesive material which fea-tured a multi-crosslinked network comprising covalent bonds,hydrogen bonds,and π-π stacking.The study systematically investigated the reg-ulation of material properties by varying the CMC-MA mass fraction(0.5%~2.0%).The resulting bamboo cellulose-based adhesive material ex-hibited equilibrium swelling ratios ranging from 6.3 to 21.3 g/g,tensile strengths from 3.1 to 5.7 MPa,and elongations at break from 180.4%to 306.5%.The optimized bamboo cellulose-based adhesive material demonstrated strong adhesion to moist porcine skin,with a shear strength of 23 kPa and an interfacial toughness of 150 J/m2,outperforming commercial tissue adhesives.The results of ex vivo organ sealing tests showed that the bamboo cellulose-based adhesive material withstood 200 cycles of cyclic expansion and contraction in a porcine heart model without detaching,and achieved rapid sealing under light pressure within 5 s in a simulated gastric acid leakage model,maintaining efficacy for 48 h,with no cytotoxicity.关键词
