In this study, the antimicrobial property and food package capability of polymethylpentene (PMP) substrate with silicon oxdie (SiO) and organic silicon (SiCH) stacked layers deposited by an inductively coupled plasma chemical vapor deposition system were investigated. The experimental results show that the stacked pair number of SiO/SiCH on PMP is limited to three pairs, beyond which the films will crack and cause package failure. The three-pair SiO/SiCH on PMP shows a low water vapor transmission rate of 0.57 g/m²/day and a high water contact angle of 102°. Three-pair thin-film coated PMP demonstrates no microbe adhesion and exhibits antibacterial properties within 24 h. Food shelf life testing performed at 28 °C and 80% humidity reports that the three-pair thin-film coated PMP can enhance the food shelf-life to 120 h. The results indicate that the silicon-based thin film may be a promising material for antibacterial food packaging applications to extend the shelf-life of food products.
在本研究中，对通过电感耦合等离子体化学气相沉积系统沉积了二氧化硅（SiO）和有机硅（SiCH）堆叠层的聚甲基戊烯（PMP）基材的抗菌性能和食品包装性能进行了研究。实验结果表明，PMP上SiO/SiCH的堆叠对数限制为三对，超过此数量，薄膜将出现裂纹并导致包装失效。PMP上的三对SiO/SiCH显示出0.57 g/m²/天的低水蒸气透过率和102°的高水接触角。三对薄膜涂层的PMP在24小时内未表现出微生物粘附并具有抗菌性能。在28°C和80%湿度下进行的食品保质期测试报告称，三对薄膜涂层的PMP可将食品保质期延长至120小时。结果表明，硅基薄膜可能是用于抗菌食品包装应用以延长食品保质期的一种有前途的材料。
