“…They include processes such as diffusion treatments, selective hardening, plating, hardfacing, thermal spray coatings, high-energy treatments such as laser processing, and organic coatings such as paints and plastic laminates [1][2][3][4][5]. Involvement with coatings dates back to the metal ages of antiquity in gold beating and gilting [6,7] and can be said to have transformed itself from what was mainly an empirical craft, into a key technology, grounded on scientific principles within a span of few decades [8][9][10]. The advances in coatings are primarily in areas relating to tailor the microstructure or the thickness.…”

This review discusses briefly the important aspects of thin films. The introduction of the article is a summary of evolution of thin films from surface engineering, their deposition methods, and important issues. The fundamental aspects of electrochemical deposition with special emphasis on the effect of temperature on the phase formation have been reviewed briefly. The field of sonoelectrochemistry has been discussed in the paper . The literature regarding the effects of temperature and sonication on the structure and morphology of the deposits and nucleation mechanisms, residual stress, and mechanical properties has also been covered briefly.

“…for biofuels) [1,15], hydrogenation (for margarine synthesis) [16,17] and modification of the double bonds, one of the most common being epoxidation [12,18]. Epoxidized oils have a variety of uses including as resins [19], as precursors of polyols for polyurethane synthesis [14,20] and for coatings [21].…”

Synthesis and Properties of Polyesters from Waste Grapeseed Oil: Comparison with Soybean and Rapeseed Oils

The aim of this study was to investigate the application of grapeseed oil, a waste product from the wine industry, as a renewable feedstock to make polyesters and to compare the properties of these materials with those derived from soybean and rapeseed oils. All three oils were epoxidized to give renewable epoxy monomers containing between 3.8 and 4.7 epoxides per molecule. Polymerisation was achieved with cyclic anhydrides catalysed by 4-methyl imidazole at 170 and 210°C. Polymers produced from methyl tetrahydrophthalic anhydride (Aradur917 Ò ) had greater tensile strength and Young's Modulus (tensile strength = 12.8 MPa, Young's Modulus = 1005 MPa for grapeseed) than methyl nadic anhydride (MNA) derived materials (5.6 and 468 MPa for grapeseed) due to increased volume of MNA decreasing crosslink density. Soybean and grapeseed oils produced materials with higher tensile strength (5.6-29.3 MPa) than rapeseed derived polyesters (2.5-3.9 MPa) due to a higher epoxide functionality increasing crosslinking. T g 's of the polyesters ranged from -36 to 62°C and mirrored the trend in epoxide functionality with grapeseed producing higher T g polymers (-17 to 17°C) than soybean (-25 to 6°C) and rapeseed (-36 to -27°C). Grapeseed oil showed similar properties to soybean oil in terms of T g , thermal degradation and Young's Modulus but produced polymers of lower tensile strength.Therefore grapeseed oil would only be a viable substitute for soybean for low stress applications or where thermal properties are more important.

“…Before, the cheaply supply of crude oil, vegetable oil have been used for painting and coating industries. But, trend has been spurred by depleted supply of fossil fuels, environmental issues and waste disposal problems (Derksen, Derksen, Pestrus, & Peter, 1995).The current utilization of renewable raw material resources by chemical industries is 10-20% and it is expected to reach up to 25% by 2020 (Lucas, 2010). Polymer industries compel from its dependence on non-renewable sources and accept industrially applicable renewable sources (Meier & Lucas, 2010).…”

Neem oil Alkyd resin (NOAR) was synthesized by alcoholysis and polycondensation using glycerol and phthalic anhydride respectively at 230-250°C. The alkyd resin was characterized by FT-IR spectroscopy, viscometry, solubility in various solvents and antimicrobial activity against some selected bacterial species. FT-IR analyses indicated the successful synthesis of alkyd resin as also evident from titrimetric determination of acid number of the mixture which decreases as the reaction progresses. Microbiological analyses of the resin show that it is active against some selected bacterial specie particularly at concentrations of 100 and 50mg/ml in DMSO. The synthesized resin was used as binder in the formulation of oil-based paints using varying resin concentration i.e. 0, 10, and 20% w/v. The prepared paints were found to have excellent fastness properties to light, water, alkali but poor to xylene. The results obtained suggested that NOAR can serve as binder with potential applications in the production of antimicrobial paints.
