“…When the polymerization is performed in bulk, high temperatures are required as well as the incorporation of a liquid diol or polyol in the formulation, namely, polyethylene glycol (PEG), 182−184 polyglycerol (PGL), 185 polypropylene glycol (PPG), 185,186 and polycaprolactone (PCL). 187 To avoid the use of diisocyanates, a variety of new materials can be obtained by polycondensation of diamines or diols with freshly prepared bis(chloroformate)s 188 and dicarbamates, 177 respectively.…”

“…Carbohydrates are reported to be embedded in PU networks using them as composites/fillers and by covalent linkage with isocyanate to form crosslinked networks . Solanki et al ., for instance, synthesized castor oil‐based PUs crosslinked with starch and reported excellent mechanical properties of the produced materials . Carbohydrates, such as cellulose or starch nanocrystals, have been used as useful fillers in PUs.…”

Several new eco-friendly materials have the potential to replace conventional petroleum-derived materials and monomers. Among them are natural polysaccharides. The use of polysaccharides in polyurethane (PU) synthesis has not yet been studied extensively, even though as multihydroxyl compounds, they can easily serve as crosslinkers in PU synthesis. One naturally occurring (hyper-) branched polymer is amylopectin, a component of starch. In this work, we report the PU synthesis and film-forming capacity using the asymmetric cyclic aliphatic diisocyanate-isophorone diisocyanate (IPDI) with acetylated and pristine partially hydrolyzed amylopectin/ white dextrin (AVEDEX W80) as a crosslinker.

“…f-RGO was used both as a reactive chain extender as well as a nano-reinforcing agent incorporating improved properties compared to the unmodied counterpart. [30][31][32] The increase in the use of environmentally friendly raw materials, environmentally benign syntheses, formulation and processing methods in research and industry has beckoned several researchers to resort to clean and green methods of syntheses. 24 Kasra and co-workers developed gold nanotube/nanowire-PU composites from CO and polyethylene glycol to develop biodegradable biomaterial scaffold with an optimum initial mechanical integrity for implantation.…”

Linseed oil polyol/ZnO bionanocomposite towards mechanically robust, thermally stable, hydrophobic coatings: a novel synergistic approach utilising a sustainable resource

et al. 2015

Linseed oil polyol/ZnO bionanocomposite was prepared to obtain mechanically robust, thermally stable, hydrophobic coatings via a novel synergistic approach utilising a vegetable oil polyol for the first time.The synthesis process obviates the use of reducing agents, surfactants, reaction media, stabilizing agents, solvents, and other chemicals. Linseed polyol serves the purpose of obtaining ZnO nanoparticles. The linseed polyol backbone hosts hydroxyl and carboxylic groups that participate in the generation of ZnO nanoparticles in the polyol matrix (ester elimination, addition-elimination reaction). The progress of the reaction was monitored by recording FTIR spectra at regular intervals of time. The coatings obtained were scratch-resistant, impact-resistant, well-adherent, flexibility-retentive and hydrophobic, showing good chemical resistance under acidic, alkaline, and salt environments. Thermogravimetric analysis revealed that these coatings could be safely used up to 250 C. The work described is consistent with the principles of "Green Chemistry" (Principles 1, 2, 3 , 4, 5, 6, 7, 8, and 12), such as utilising a renewable feedstock, resorting to a solventless approach, and employing safer chemistry. The results showed that these coatings may be well employed as promising candidates towards environmentally friendly corrosion protective coatings.
