“…1,[5][6][7] The commercial production began in 1933 at General Electric and then, was followed by other companies. 1,4,8 Indeed, commercial success of the alkyd resins has been supported by their great properties which can be modified by changing the oil length, and their compatibility with a number of polymers which makes them very versatile polymers to produce a broad range of coating materials for numerous applications. 1 However, in the 1950s, the emergence of emulsion polymerization technology driven by acrylic and vinyl polymers made it possible to produce water-based paints which captured the majority of the coatings market.…”

“…11,12 Their use is limited by European regulations to avoid harmful environmental impact, such as air pollution. 1,8,13 Therefore many research studies have been focused on the development of water-based alkyd coatings, in order to formulate zero VOC paints. 1 Unfortunately, these water-based alkyd coatings have not achieved the same performances as solvent-based alkyd coatings.…”

This review highlights both the various polymers grafted to alkyd resins reported in the literature and the different routes to synthesize these alkyd hybrids. Alkyd resins were discovered in the mid-1920s. Then, they quickly found a prominent place among coatings and paint binders thanks to their numerous advantages such as good heat resistance, excellent gloss, and low cost. Nevertheless, in the 50s, the emergence of new synthetic polymers with better properties (chemical resistance, mechanical and thermal properties) such as epoxy, acrylic or polyurethane, weakened the position of the alkyd resins among coating industry. Nowadays, due to global issues such as health and environmental concerns, research focuses on biobased polymers. Since, alkyd resins are mainly biobased, they have gained increasing attention in the last decade. Nevertheless, the issue of using volatile organic compounds (VOC) and the urge of replacing them, have led to the development of new synthetic routes. Moreover, in order to enhance alkyd properties and bridge the gap with new materials, other polymers such as epoxy, acrylates, polyurethanes or siloxanes were used to form alkyd hybrids. Hence, the different strategies to perform alkyd hybrids are detailed and discussed in this review. Furthermore, composites made with alkyd hybrid matrix are presented. Finally, the perspectives about the future developments of alkyd hybrids and the most promising hybrids are discussed.

“…As a side product of the soy-oil production, the soy protein isolate (SPI) has become an eco-friendly alternative to fossil products due to its inherent advantages of cost-effective, biodegradable, abundant, etc. [7,8,9,10]. However, the SPI derivatives are especially low water-resistance and poor mechanical properties that restrict their industrial applications [11,12].…”

The soy protein isolate (SPI), sodium dodecylbenzenesulfonate (SDBS) and pentaerythritol glycidyl ether (PEGE) were used to make biodegradable films in this study. Unlike the usual method that adding sodium hydroxide (NaOH) during the SPI-based film casting, SDBS was used as a surfactant playing the similar role as NaOH. Since NaOH is a chemical with corrosiveness and toxicity, the replacing of NaOH by SDBS might reduce the hazard threat during the utilization of SPI-based films in food packing application. Furthermore, the presentation of SDBS helped dispersing the hydrophobic PEGE into the hydrophilic SPI. PEGE is a crosslinking agent with multiple reactive epoxy groups. The chemical structures and micro morphologies of the fabricated films were investigated by means of FTIR, XRD, and SEM. The thermal stabilities of the films were examined by means of the thermo-gravimetric analysis. After the chemical crosslinking, the ultimate tensile strength of the film was significantly increased, meanwhile, the water absorption was dramatically decreased. It was concluded that the SPI-based film containing 4% PEGE achieved the optimal performance.

“…As a by-product in the edible oil industry, soy protein isolate (SPI) has advantages of inexpensive, biocompatible, renewable, etc., providing an environmentally-conscious alternative to fossil fuel sources [6][7][8][9]. However, the drawbacks of low strength [10] and high moisture absorption [11] limit the applications of SPI products.…”
