Abstract

In this work, poly(itaconic anhydride-co-acrylamide) copolymer was synthesized by free radical solution copolymerization and poly(itaconic anhydride-co-acrylamide)/nanoclay nanocomposites were prepared by in situ interlamellar copolymerization with three different loading of nanoclay. Intercalation and formation of nanostructures were clarified by spectroscopic techniques. The interaction/compatibility between nanoclay and the copolymer was verified by following the characteristic bands of nanoclay and functional groups in the ATR-FTIR spectra. The increase in d-spacing between silicate layers in nanocomposites was determined from XRD analysis. The thermal and viscoelastic properties of nanomaterials and the effect of simultaneous addition of nanofiller were evaluated by thermogravimetric and dynamic mechanical analysis. It was observed that nanocomposites reinforced with nanoclay had higher thermal stability than pristine poly(itaconic anhydride-co-acrylamide) and thermal stability increased proportionally with amount of nanoclay loaded. The improvement effect of the incorporated nanoclay on the storage modulus was observed at higher temperature values for the nanocomposite loaded with 4 % nanoclay.
