Heidorian electrostatic spraying. They investigated the corrosion performance


Heidorian
M et al. 2010 35 characterized of structure and anticorrosive behavior of polyurethane/organoclay nanocomposite coatings
which was prepared by dispersing of OMMT clay (organoclay) in nanoscale
in polyurethane matrix via ultrasonication
assisted process. Corrosion protection of PU/OMMT nanocomposite coatings was improved with increased the organoclay loading
up to from 1%wt to 3%wt.

Pizza D et al. (2012) 36 influence of montmorillonite clay nanoparticles on
polyester-based powder coatings which were applied on AISI 1008 carbon steel electrodes by electrostatic spraying. They investigated
the corrosion performance with 2wt% and
4wt% of montmorillonite (MMT) using salt test and characterized this
samples via many techniques (e.g. XRD, DSC,
TEM, TGA). From transmission electron- microscopy they got on an
exfoliated structure with the presence of MMT
clay in coatings and better anticorrosive performance than without a
presence MMT clay.

Piromruen P et al. (2014) 37 obtained polyaniline/montmorillonite nanocomposite
(PANI/Mt) by a used amount of clay about 1% to 7% (w/w). they synthesized this
type of nanocomposites via in situ chemical oxidative polymerization. From Fourier transform infrared FTIR and scanning
electron microscopy (SEM) refers to a combination
of clay with PANI matrix, however from X-ray diffraction they observed
exfoliated structure but the corrosion protection was investigated by cyclic
voltammetry when applied PANI/Mt nanocomposite coatings on steel bodies against
1.0 M H2SO4 They reached many results as follows:

·      
the anticorrosive
properties were improved by adding Mt clay to PANI enhanced comparison pure PA.

·      
 thermal properties enhanced with increasing Mt
level.

·      
 when applied film with thickness 50 µm on
steel the best corrosion resistance to salt spray it was by obtained 5% (w/w)
Mt clay.
