以壳聚糖/吐温80/玫瑰果籽油为成膜乳剂，以分散蒙脱土纳米粘土C30B为载体，通过浇铸法制备生物聚合物纳米复合膜。研究了组成对复合材料的结构、形态特征、力学性能、阻隔性能、抗菌性能和抗氧化性能的影响。玫瑰果籽油在壳聚糖薄膜中的存在导致了柔性薄膜的形成，该薄膜具有更好的机械、气体和水蒸气阻隔性能以及抗氧化性。对大肠杆菌、伤寒沙门氏菌和蜡样芽孢杆菌的体外抑菌试验表明，壳聚糖/玫瑰果油/蒙脱土纳米粘土复合材料对这三种微生物均有较好的抑制作用。
Biopolymer nanocomposite films were prepared by casting film-forming emulsions based on chitosan/Tween 80/rosehip seed oil and dispersed montmorillonite nanoclay C30B. The effect of composition on structural, morphological characteristics and, mechanical, barrier, antimicrobial and antioxidant properties was studied. The presence of rosehip seed oil in chitosan films led to the formation of flexible films with improved mechanical, gas and water vapour barrier properties and antioxidant activity. The in vitro antibacterial tests against Escherichia coli, Salmonella typhymurium, and Bacillus cereus showed that the chitosan/rosehip seed oil/montmorillonite nanoclay composites effectively inhibited all the three microorganisms.
