摘要：以鱼鳞明胶（SG）和壳聚糖（CS）为原料，薰衣草精油（LEO）为抗菌剂，通过共混法制备了抗菌复合
膜（SG/CS/LEO），通过 FTIR、XRD、SEM 和热重分析对复合膜进行了表征，并对其力学性能、光学性能、阻
隔性能、抑菌性能进行了测试。结果表明，LEO 与 SG/CS 基膜较好地复合，与 SG/CS 基膜相比，当 LEO 添加
量（以明胶/壳聚糖成膜液体积计，下同）为 1.00%时，复合膜拉伸强度下降了 10.46%，但仍具有良好的力学强
度〔(26.36±0.45) MPa〕，断裂伸长率提升了 12.96%；透明度有所下降，透光率下降了 8.70%；耐水性能和水蒸
气阻隔性能显著增强，含水率、水溶性和水蒸气透过率分别下降了 22.48%、30.49%和 26.41%；DPPH 自由基清
除率提高了 247.88%，抗氧化性显著提高；同时对大肠杆菌和金黄色葡萄球菌具有良好的抑菌作用。

Abstract: Antibacterial composite film was prepared by blending fish scale gelatin (SG) with chitosan (CS)
and lavender essential oil (LEO). The composite film obtained was then characterized by FTIR, XRD, SEM
and thermogravimetric analysis, followed by evaluation on its mechanical, optical, barrier and antibacterial
properties. The characterization results showed that LEO was well blended into SG/CS base film.
Compared with the control SG/CS base film, at LEO content (based on the volume of SG/CS film forming
solution, the same below) of 1.00%, the composite film displayed a tensile strength reduction by 10.46%,
elongation at break increase by 12.96%, transparency decrease by 8.70%, DPPH radical scavenging rate
elevation by 247.88%, and decrease of water content, water solubility and water vapor transmittance by
22.48%, 30.49% and 26.41%, respectively, while still exhibited good mechanical strength [(26.36±
0.45) MPa] and significantly enhanced water resistance and water vapor barrier performance. Meanwhile,
the composite film showed significant improvement in oxidation resistance and good inhibitory effect on E.
coli and S. aureus.
