Flame retardant UV-curable acrylated epoxidized soybean oil based organic–inorganic hybrid coating

Mechanical properties of sol–gel coatings on polycarbonate: a review

“…The interest is that those resins are applied in a wide range of application (coatings, adhesives, resin matrices, etc), they are adherent to many substrates, and they are also temperature and solvent resistant. As logically expected, reported studies [4,22,23,57,58] show a decrease in hardness with an increasing (resin)/(inorganic part) ratio, since the organic part bring ductility and flexibility and inorganic network cross-linking becomes less effective. Altintas et al [23] prepared a series of UV-curable I/O hybrid based on TEOS and MEMO as silica precursors and maleimide-modified epoxy resin and urethane acrylate oligomer as organic content.…”

“…Indeed, with the increasing inorganic content of the material, hardness and abrasion resistance are improved. The group of Gungor reports the same conclusion using close systems [4,22]. Another example, reported by Wouters et al [24], concerns a system based on acrylate, polyurethane resin, MEMO and TEOS.…”

“…7) [23-25, 58, 59, 75]. UV curing is often coupled with the traditional oven curing to optimize reticulation degree and then mechanical properties [6,16,17,22,58,62,76]. Even if numerous works report the use of UV-curing for sol-gel UV-curable system on polycarbonate, researchers use this process to densify the network but do not study relationship between UV-curing conditions and mechanical properties of the final coating.…”

“…These precursors, which have to be thermally or photo-chemically cured leads to an organic network, tangled up to the inorganic one. Close to this approach, it is also reported that the addition of pure organic monomers to the network former performs a double reticulation and creates a convolution of both O/I networks [4,10,[22][23][24][25]. In any case, sol-gel process mastery is primordial to prepare a stable sol, able to be deposited and reticulated in a three dimensions O/I hybrid network.…”

Biorenewable thermosetting copolymer based on soybean oil and eugenol

“…AESO has also been combined with hemp fibers [25], cellulose fibers [28], pyrolyzed chicken feather [29], and montmorillonite clay [30] to produce composites with high renewable content. In addition, it has been proposed that AESO-based resins can be used in electronics [31,32] and coating applications [33].…”
