Fabrication of Poly(o-Chloroaniline) to MMT Clay as Potential Flame-Resistant Material

Abstract

Polyorthochloroaniline (POC) nanocomposites with montmorillonite (MMT) clay (POC/MMT) nanocomposites (POC/MMT clay NCs) are the most widespread and attractive among organic/inorganic nanocomposites due to their distinctive properties in addition to inexpensive, abundance, and attractive characteristics such as ion-exchange and great surface area properties and have ample applications. The preparation of polyorthochloroaniline nanocomposites with montmorillonite (POC/MMT) clay nanocomposite has been completed chemically with the help of oxidative polymerization of orthochloroaniline in the presence of montmorillonite (MMT) clay. POC will be admixed with montmorillonite (MMT) clay at various concentrations, by keeping the o-chloroaniline monomer in the reaction mixture constant. To investigate the influence of MMT clay on the characteristics of POC, the load percentage of MMT clay in the nanocomposites was adjusted. The characterization and properties have been determined by using different techniques. FTIR spectroscopy was used to investigate the interactions between POC and MMT. The complete homogeneous dispersion of MMT clay in the POC matrix was examined by scanning electron microscope (SEM) analysis that revealed the compactness. The thermal stability of polymer–clay nanocomposites was determined by thermogravimetric analysis (TGA). The results of DSC/TGA measurements revealed that the flame retardancy and thermal stability of POC/MMT clay nanocomposites were considerably improved.
