| 英文摘要 | Globular structured oleo alkyds possess low viscosity, good fluidity, and play an important role in the generation of volatile organic compound (VOC) free paints and coatings. Soya oil (SO), an abundant, inexpensive, renewable, and sustainable material is one of the examples of such oleo alkyd precursors that meets the requirement of green chemistry. The present work reports the synthesis of hyperbranched soya alkyd based nanocomposite coatings and their corrosion inhibition efficiency. Hyperbranched alkyd (HBA) was synthesized using SO, pentaerythritol, and phthalic anhydride. The magnetite (Fe3O4) nanoparticles were dispersed via sonication in butylated melamine formaldehyde (BMF) modified HBA (HBABMF) to formulate the nanocomposite (HBABMFFe(3)O(4)) anticorrosive coatings. The ASTM methods were used to evaluate structural, morphological, physicomechanical, thermal, electrochemical, and anticorrosive properties of these coatings. The HBA has a globular structure with the good degree of branching (DOB = 0.69). HBABMF and HBABMFFe(3)O(4) nanocomposite coatings showed good flexibility and physicomechanical properties. The inclusion of Fe3O4 nanoparticles enhanced the load bearing capacity of nanocomposite coatings by dissipating the instantaneous energy in scratch and impact tests. Electrochemical corrosion studies revealed that the HBABMFFe(3)O(4) nanocomposite coatings exhibit superior corrosion resistance performance (impedance = 10(7) Omega and corrosion rate 1.0 x 10(4) mils per year (mpy) than that of HBABMF and other similar reported coating systems. |
