Plant oil-based waterborne polyurethanes: A brief review
(Tech Science Press, 2020-03)
The increasing pressure from consumers and policy makers to reduce the use of synthetic polymers, whose production contributes to the depletion of non-renewable resources and are usually non-biodegradable, has prompted the ...
Cellulose nanocrystal reinforced acylglycerol-based polyurethane foams
(Budapest University of Technology and Economics, 2020-05)
This work presents the preparation of polyurethane composite foams based on castor oil or modified canola oil as a polyol, and cellulose nanocrystals (CN) as nanofiller (0.10, 0.25, and 0.50 wt% of CN content). The bio-based ...
Enhancement of thermal stability, strength and extensibility of lipid-based polyurethanes with cellulose-based nanofibers
(Elsevier B.V., 2012-10-01)
Cellulose was extracted from lignocellulosic fibers and nanocrystalline cellulose (NC) prepared by alkali treatment of the fiber, steam explosion of the mercerized fiber, bleaching of the steam exploded fiber and finally ...
Self-healing ability based on hydrogen bonds in organic coatings for corrosion protection of AA1200
(2020-12-01)
Biobased polyurethane coatings derived from vegetable oils, with 2 different compositions, were prepared and applied on the AA1200 aluminum alloy to confer corrosion protection. The influence of the ratio between the ...
Comparative effects of two different crosslinkers on the properties of vegetable oil-based polyurethanes
(John Wiley & Sons Inc, 2020-06)
Thermoset polyurethanes (PUs) were prepared from a polyol derived from castor oil, 4,4′-methylene diphenyl diisocyanate (MDI) and different trifunctional low-molecular-weight crosslinkers, biobased glycerol (Gly) and ...
Highly functional lactic acid ring‐opened soybean polyols applied to rigid polyurethane foams
(John Wiley & Sons Inc, 2019-05)
We synthesized polyols with high hydroxyl functionalities (FOHs), between 9.0 and 12.6, and characterized them with differential scanning calorimetry, thermogravimetric analysis, and size exclusion chromatography after we ...
