Fourier transform infrared spectroscopy nanocomposites

This is a nonpolar rubber with very little unsamration. Nanoclays as well as nanotubes have been used to prepare nanocomposites of ethylene-propylene-diene monomer (EPDM) rubber. The work mostly covers the preparation and characterization of these nanocomposites. Different processing conditions, morphology, and mechanical properties have been smdied [61-64]. Acharya et al. [61] have prepared and characterized the EPDM-based organo-nanoclay composites by X-ray diffracto-gram (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy... 

A Fourier transform infrared spectroscopy (FTIR) study was obtained by using Perkin-Elmer spectrometer 100, USA. Prior to this analysis, kenaf whiskers were mixed with KBr to prepare homogeneous suspensions and afterwards pressed into transparent pellets and analyzed in transmittance mode within the range of 4000-500 cm. In the case of thin nanocomposite film (Cellulose Acetate Butyrate [CAB] and kenaf whiskers) the analysis was done within the range of 4000-500 cm transmittance mode. 

Fourier transform infrared spectroscopy (FTIR) may find a difference between the bonding in different types of nanocomposites however, the variations could be minute and hence this is an unreliable method for nanocomposite characterization [53, 54]. Nascimento et al. [55] presented for the first time the resonance Raman characterization of a polymer/clay nanocomposite formed by aniline polymerization in the presence of MMT. 

Un-OH can also be copolymetized with propene on a MAO-pretreated glass surface by Et(Ind)2ZrCl2. Parts of the resulting copolymer are chemically bonded to the surface, as shown by extraction experiments, scanning electron microscopy (SEM) microscopy as well as Fourier transformation infrared spectroscopy (FUR) analysis. Similar results were reported for the copolymerization of ethene with Un-OH by the same catalyst system on the organically modified silicate montmorillonite (OMMT) resulting in PE-Un-OH/OMMT nanocomposites which consist of well-exfoliated OMMT dispersions and controlled degrees of PE functionalization. ... 

Chemical structure The chemical structure of polymer/filler nanocomposites is generally identified by Fourier transform infrared and solid-state spectroscopy [36].
