Transparent And Flame Retardant Vinylidene Chloride-Methyl Acrylate Hybrid Films With Enhanced Water Vapor Barrier, Thermostability, And Anti-Glare Properties
JOURNAL OF APPLIED POLYMER SCIENCE(2021)
摘要
Flexible organic light emitting diodes (FOLEDSs) require a barrier layer with transparency, thermal stability, and flame retardance to prevent water from inducing the corrosion of electrode and ultimately deterioration. Herein, HPS spheres were incorporated into the vinylidene chloride-methyl acrylate (VDC-MA) matrix to enhance the water vapor barrier property, thermostability, and anti-glare effect. Scanning electron microscopy showed that HPS spheres were more compatible with VM (89.86-10.14) by presenting better water vapor barrier property rather than with VM (92.38-7.62). The anti-glare effect of composite film was improved with HPS spheres, while the transparency still maintained over 80%. Thermogravimetric analysis showed that the weight loss still maintained over 50% with the incorporation of HPS spheres, indicating significant improvement compared with control VDC-MA films. Our research supplies an effective approach to prepare transparent and flame retardant hybrid films with enhanced water vapor barrier, thermostability, and anti-glare properties, which is promising in the encapsulation of FOLEDSs and other electronics areas.
