分形纳米二氧化硅/PBAT纳米复合薄膜制备及性能研究
Preparation and Performance Study of Fractal Nano Silica/PBAT Nanocomposite Films
摘要
Abstract
Poly(butylene adipate-co-terephthalate)(PBAT)is an environmentally friendly biodegradable packaging material,but its poor mechanical properties and lack of antibacterial properties limit its application in packaging materials.The fractal structure silica nanoparticles(FSN)were prepared and modified by 3-aminopropyl tri-ethoxysilane and loaded with silver nanoparticles(FSN-Ag).The FSN-Ag were added to PBAT polymer matrix as filler,and the PBAT-FSN-Ag composite films were prepared by solution casting method.The effects of the amount of FSN-Ag on the mechanical properties,thermal properties,optical properties,hydrophobic properties and antibacterial properties of PBAT films were studied.The results showed that the tensile strength of the composite film increased significantly with the increase of FSN-Ag content,and the composite film showed good thermal stability.When only a small amount of FSN-Ag was added,the composite film showed excellent antibacterial effect.PBAT-FSN-Ag composite film has a good application prospect as an active packaging material.关键词
