Estudo do processo de intercalação via solução PVP-bentonita. A avaliação da influência do tempo reacional, da proporção de polímero-argila e da massa molar média

Abstract

In this paper were produced reactions by solution PVP-bentonite, natural and modified, where we studied the influence of reaction time (15, 30, 45 minutes, 1, 24, 48, 72 hours), polymer-clay ratio (2:1, 1:1, 1:2) and molar mass (PVP K-30, PVP K-90). Techniques such as XRD, FTIR and TGA were used to explain the formation of intercalated nanocomposites and their reaction process.
