Abstract
- In this study, the antimicrobial property and food package capability of polymethylpentene (PMP) substrate with silicon oxdie (SiO<subscript>x</subscript>) and organic silicon (SiC<subscript>x</subscript>H<subscript>y</subscript>) 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<subscript>x</subscript>/SiC<subscript>x</subscript>H<subscript>y</subscript> on PMP is limited to three pairs, beyond which the films will crack and cause package failure. The three-pair SiO<subscript>x</subscript>/SiC<subscript>x</subscript>H<subscript>y</subscript> 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. [ABSTRACT FROM AUTHOR]
