EFEITO DO TEOR DE GLICEROL NO TRANSPORTE DE VAPOR D’ÁGUA ATRAVÉS DE FILMES DE TRIACETATO DE CELULOSE PRODUZIDOS A PARTIR DO APROVEITAMENTO DA PALHA DE MILHO (ZEA MAYS L.)

Glycerol is a plasticizer widely used due to its good plasticization efficiency, great availability, biocompatibility and low exudation. It is a renewable raw material that, when introduced in biodegradable films, promotes significant changes in its properties and, thus, guarantees a wide spectrum of application. In this work, corn straw was used to produce cellulose triacetate films from mixtures with glycerol (10%, 20% and 30%). The films were characterized by X-Ray Diffraction, Scanning Electron Microscopy, Thermogravimetric Analysis, Water Vapor Transport Rate and Water Vapor Permeation. T...
