Experimental Investigation using FTIR of Injection Moulded Alumina and TiO2 Filled PP- Composites

Abstract

The integration of inorganic particles in polymer has become an effective approach to develop new material due to steadily increasing concept of sustainability.  In addition to the bulk matrix and filler any composite also consists of the so-called interfacial region, comprising the matrix between the bulk matrix and filler. Due to its nearness to the surface of the filler, the properties of polymer in the interfacial region differ from those of the bulk matrix.This paper describes the FTIR behavior of Polypropylene (PP) filled with alumina powder, TiO₂ in 5-20 wt% composite, which were prepared by plastic injection moulding machine (PIM).
