“…in industry are constantly looking for alternatives as the price of fossil oil is typically increasing. Recently, the synthesis of waterborne PU dispersions derived from vegetable oil such as soybean oil, castor oil, rapeseed oil and linseed oil have been reported Lu, 2012, 2013;Lu and Larock, 2008;Ni et al, 2010). However, to the best of our knowledge, no research has been reported concerning jatropha oil regarding its promising properties to produce waterborne dispersions.…”

Tannic-acid-based low volatile organic compound-containing waterborne hyperbranched polyurethane was prepared. In order to improve the performance, it was modified in an aqueous medium using a glycerol-based hyperbranched epoxy and vegetable-oil-based poly(amido amine) at different wt%. The combined system was cross-linked by heating at 100°C for 45 min. Fourier transform infrared spectroscopy and swelling study were used to confirm the curing. A dose-dependent improvement of properties was witnessed for the thermoset. Thermoset with 30 wt% epoxy showed excellent improvements in mechanical properties like tensile strength (~3.4 fold), scratch hardness (~2 fold), impact resistance (~1.3 fold), and toughness (~1.7 fold). Thermogravimetric analysis revealed enhancement of thermal properties (maximum 70°C increment of degradation temperature and 8°C increment of T g ). The modified system showed better chemical and water resistance compared with the neat polyurethane. Biodegradation study was carried out by broth culture method using Pseudomonas aeruginosa as the test organism. An adequate biodegradation was witnessed, as evidenced by weight loss profile, bacterial growth curve, and scanning electron microscope images. The work showed the way to develop environmentally benign waterborne polyurethane as a high-performance material by incorporating a reactive modifier into the polymer network. Use of benign solvent and bio-based materials as well as profound biodegradability justified eco-friendliness and sustainability of the modified system.

Vapor-grown carbon nanofiber (CNF)-modified soy polyol-based polyurethane (PU) nanocomposites with different hydroxyl value of polyols (OH) were synthesized. The glass transition, thermal stability, mechanical properties, and morphology of the PU nanocomposites were characterized through differential scanning calorimetry, thermogravimetry, universal test machine, and scanning electron microscopy. The addition of CNFs increased the glass transition temperature as well as significantly improved tensile strength and Young's modulus of PU nanocomposites. Meanwhile, thermal and mechanical properties of PU composites were influenced by the different hydroxyl value of polyols due to those different structures. In particular, in the case of 2 mass% CNF addition in PU derived from soy polyol with the OH number of 164 mg KOH g -1 , 20.8°C improvement in the glass transition temperature, 115 % increment in tensile strength, and nearly eightfold increase in Young's modulus were obtained.
