Preparation and properties of bacterial cellulose-ZnO/waterborne polyurethane composite films

  • 摘要: 以细菌纤维素(BC)为模板,以ZnSO4、NaOH和尿素为原料,通过水热法制备了具有新型刷状结构的细菌纤维素-ZnO(BC-ZnO)复合颗粒,尺寸约为3~5 μm,其中BC含量约为19wt%,并对其可能的形成机制进行阐述。将不同含量的BC-ZnO复合颗粒通过原位聚合法引入到水性聚氨酯(WPU)中得到细菌纤维素-ZnO/水性聚氨酯(BC-ZnO/WPU)复合薄膜,对复合膜的结构与性能进行了表征。结果表明:复合颗粒在WPU中分散良好;复合膜的拉伸强度在BC-ZnO含量为1.0wt%时达到最高,相较于纯WPU提高了84.6%;吸水率从16.5%降到4.9%;BC-ZnO的引入提高了复合膜的初始热稳定性;复合膜具有良好的抗菌性,当BC-ZnO含量为1.3wt%时,对金黄色葡萄球菌的抗菌率超过99%,对大肠杆菌的抗菌率超过85%。
