Investigation on structural, mechanical and melt flow properties of in situ polypropylene/kaolin nanocomposite

The effect of Kaolin (K) filler particles and un-grafted maleic anhydride (MA) as coupling agent incorporated with dicumyl peroxide (DCP) on the structural, mechanical, and melt flow index properties of polypropylene (PP) were investigated. PP was filled with varied weight percentages of K and MA/DC...

Description
Summary:The effect of Kaolin (K) filler particles and un-grafted maleic anhydride (MA) as coupling agent incorporated with dicumyl peroxide (DCP) on the structural, mechanical, and melt flow index properties of polypropylene (PP) were investigated. PP was filled with varied weight percentages of K and MA/DCP using in-situ process. The polypropylene/kaolin (P/K) nanocomposites (NCs) with 1 wt.%, 3 wt.% and 5 wt.% each of K, MA & DCP at different compounding process parameters were made using the two-roll mixer. It was evident that there was increased in the tensile strength with addition of K filler at 3 wt.% of 13.51% which is the highest in K with MA/DCP at 5 wt.% of 14.43%. The impact strength also improved significantly with the increase of 27% and 15% observed in Polypropylene/Kaolin/Maleic anhydride/Dicumyl peroxide (PKMDCP) 3 and Polypropylene/Kaolin (PK) nanocomposites (NCs), respectively. Melt flow indices decreased thereby increasing the viscosity of the NCs due to presence of the K filler and MA/DCP.
