Abstract

The incorporation of multi-walled carbon nanotubes (MWCNT- COOH) and graphene oxide (GO) nanoparticles into poly(acrylamide-co-acrylic acid) poly(AAm-co-AA) have been investigated. FTIR demonstrated that GO, functionalized MWCNTs and poly(AAm-co-AA) polymer have good interfacial bonding. The nanocomposites were prepared using a simple casting method in separate experiments. The thermal properties like glass transition temperature (Tg) and melting point were elucidated by using Differential Scanning Calorimetric (DSC), the results reveal that the thermal properties were changed after incorporation of CNTs and GO into the poly(AAm-co-AA) matrix. The young’s modulus was raised at 5% poly(AAm-co-AA) and 0.3% CNTs-COOH.
