Effect of functionalized silica nanoparticles on the mass transfer process in active PLA nanocomposite films obtained by supercritical impregnation for sustainable food packaging
Sepulveda, Javiera; Villegas, Carolina; Torres, Alejandra; Vargas, Esteban; Rodriguez, Francisco; Baltazar, Samuel; Prada, Alejandro; Rojas, Adrian; Romero, Julio; Faba, Simon; Galotto, María J. (2020)Nanocomposite films based on PLA with 1.0 % w/w silica nanoparticles (NP) and surface-functionalized silica nanoparticles with lactic acid (NP-LA), respectively, were obtained by extrusion process. Subsequently, cinnamaldehyde ...
