“…This result indicates that the d ‐spacings between layers are so large that the fillers formed exfoliated structures . This exfoliation may have been brought about by the side chains of the polymer matrix dispersing into the spaces among layers to exfoliate the layers, which are facilitated by the reaction between the tallow modifier chains of OMMT and the PULFA matrix . The appearance of broad peak in XRD also supports the amorphous nature of OBNC as also observed in an earlier publication …”

The present work describes the synthesis and characterization of polyurethanamide/organo-montmorillonite bionanocomposites (OBNC) from Linseed oil-a renewable resource. The aim of the work is (i) to widen the scope of application and improve the performance of vegetable oil based polymers, and (ii) to investigate the effect of introduction of modified clay on their structure, morphology, thermal stability, and coating properties. OBNC has been prepared by in situ polymerization of Linseed oil derived diol fattyamide and tolulylene-2,4-diisocyanate in the presence of different contents of OMMT (0.5-2.5 mass % in minimum amount of dimethylformamide) at room temperature. OBNC has been characterized by optical microscopy, FTIR, XRD, TEM, and TGA, which confirm the formation of OBNC. OBNC produced tough, scratch-resistant, impact resistant, flexibility retentive coatings, which cure at room temperature with improved coating performance and thermal stability than virgin polymer. Amongst all the compositions, OMMT-1.5 showed the best coating properties, with good scratch hardness (3.5 kg), impact (passes 200 lb/inch.) and bent test values (passes 1/8 inch). It can be commercially used as effective green coating material in future.

“…The higher surface hardness as compared both to the nonpigmented alkyd fi lm and to the paint with Pig F (starting hematite) is an indirect indication of the presence of soaps formed by reaction between the unsaturated fatty acids and the zinc and magnesium cations [42].…”

“…The higher shear levels effects were achieved by vigorous mechanical mixing and they were intensified by adding large amounts of clay and optimized matrix viscosity. 11 Lin et al 12 have worked on preparation and morphologies of the biodegradable glycerolbased alkyd resins/layered silicates nanocomposites, as well as their thermal stabilities and mechanical properties. 12 Although the mechanical properties of these glycerol-anhydride alkyd resins/clay nanocomposites were greatly improved, Lin et al still had a problem how to minimize the formation of aggregates in the case of mica or talk within the alkyd resin matrix.…”

The properties changes of the nanocomposite coatings were attributed to the modification of coating structures and different diffusion behavior in the nanocomposite coatings compared to the conventional coatings.…”

Alkyd resin based nanocomposite coatings filled with different content of silicon oxide (SiO 2 ) and titanium oxide (TiO 2 ) nanoparticles (2 and 4 wt / wt %) were prepared by solvent casting method. Characterization of the prepared nanocomposite coatings was performed by Differential Scanning Calorimetry (DSC) and Scanning Electron Microscope (SEM). The nanocomposite coatings were also tested for their Chemical stability, Mechanical properties, Abrasion and Impact resistance. DSC analysis shown that all the characteristic temperatures (glass transition temperature-T g , reaction temperature-T r ) were shifted to lower values by increasing the nanoparticle content. Mechanical characterization confirmed good elasticity with bending of f=2cm and impact resistance of 1 kg/cm 2 . Increasing the nanoparticle content, the wear resistance was changed as well. Better abrasion resistance was registered for nanocomposite coatings with SiO 2 nanoparticles compared to nanocomposites with the same content of TiO 2 .
