Effect of organoclay on structure, morphology, thermal behavior and coating performance of Jatropha oil based polyesteramide

Journal Article

2017

Jatropha oil (JO) is an inedible oil mainly used
in biodiesel. We have attempted to prepare a JO-based
polyesteramide/clay composite using a one-pot, two-step
reaction, for application as a protective coating. The aim
of the work is to utilize JO for its value-added application
by preparing a JO polyesteramide/clay composite, to
investigate the potential of the prepared composite as a
protective coating, and also to study the effect of loaded
clay on the structure, morphology, thermal stability and
coating properties of the composite. The formation of
composites was confirmed by Fourier transform infrared
spectroscopy (FTIR), transmission electron microscopy
(TEM) and atomic force microscope (AFM) studies. The
coating properties were studied by standard physicomechanical
and corrosion resistance tests in corrosive
media (3.5 wt% HCl, 3.5 wt% NaCl and tap water). The
thermal stability was assessed by differential scanning
calorimetry (DSC), thermogravimetric (TGA) and derivative
thermogravimetric (DTG) analyses. The coatings
showed good physico-mechanical and corrosion resistance
performance and can be safely used up to 275°C. The
approach paves way towards an alternate value addition
to a non-edible oil.
