摘要:
将聚乳酸(PLA)短纤纱与聚乙烯醇(PVA)/海藻酸钠(SA)混合水凝胶溶液复合,经冷冻、解冻、浸泡和干燥后获得水凝胶复合纱线,并进一步进行矿化处理。通过扫描电子显微镜(SEM)、能谱(EDS)、红外光谱(FTIR)、吸水率和拉伸测试对试样的形貌结构、元素组成、基团变化、亲水性和力学性能表征分析。结果表明:复合纱线中水凝胶成功披覆纱线表面并渗透入纱线内部,在纱线表面形成三维微孔结构;经矿化处理后,纱线表面沉积大量磷灰石,且磷灰石含量多于纯PLA短纤纱;与纯PLA短纤纱相比,复合纱线吸水率增加约50%,力学性能增强。该制备所得复合纱线具有良好的体外生物活性、吸水性和力学性能,可用于构建组织工程支架材料。
