以玉米淀粉（corn starch,CS）为基质、柠檬酸为交联剂、纤维素纳米晶（cellulose nanocrystals,CNC）乳化陈皮精油（orangepeelessentialoil,OPO）制备的Pickering乳液为抗菌剂，采用流延法成功制备了CS/CNC-OPO抗菌复合膜；探讨了CNC和OPO的添加量对CS/CNC-OPO抗菌复合膜的机械强度、水蒸气透过率、水接触角、抗菌性能等的影响，并采用傅里叶变换光谱、X射线衍射光谱和扫描电子显微镜对CS/CNC-OPO抗菌复合膜进行表征。结果表明，当OPO添加量为11%,CNC和OPO比例为1∶11（g/mL）时，CS/CNC-OPO膜的性能最好，水蒸气透过率为1.03×10-3 g/（m·h·kPa），水接触角为74.53°，拉伸强度达6.01 MPa，...

Using com starch(CS)as the film substrate,citric acid as the crosslinking agent,and Pickering emulsion prepared with cellulose nanocrystals(CNC)-emulsified orange peel essential oil(OPO)as the antibacterial agent,an antibacterial composite film(CS/CNC-OPO)was successfully prepared by the casting method.The effects of different contents of CNC and OPO on the mechanical strength,water vapor transmission rate,water contact angle and antibacterial properties of the composite film were analyzed,and the composite film was characterized by Fourier tra...
