摘要: Abstract In this work, SiO 2 nanoparticles (NPs) were modified with bovine serum albumin (BSA) under ultrasound irradiations as a green and fast route to achieve their good dispersion. Subsequently, different weight percentages of the NPs (3, 6, 9 wt%) incorporated in poly(vinyl chloride) (PVC) matrix. Thermogravimetric analysis -BSA indicated that 12 wt% modifier was loaded on surface NPs. Encapsulation resulted meaningful improvement optical, mechanical thermal characteristics prepared PVC nanocomposites (NCs). X-ray diffraction (XRD) patterns for PVC/SiO NCs showed crystalline behavior NC 6 wt% originated from phosphate buffer Water contact angle hydrophilicity enhanced increasing contents.
