Castor oil-based polyurethanes containing cellulose nanocrystals
(Wiley, 2011-06-23)
Partially foamed and nanocellulose-reinforced polyurethanes (PU) based on castor oil (CO) were prepared and their different properties were measured and related to their structures. A castor oil-based polyol (COPO) was ...
Polyurethane elastomers-based modified castor oil and poly( -caprolactone) for surface-coating applications: Synthesis, characterization, and in vitro degradation
(Journal of Elastomers and Plastics, 2014)
Polyurethanes (Pus) were synthesized from castor oil and modified through transesterification by pentaerythritol, poly(ε-caprolactone)diol (PCL), and isophorone diisocyanate to form PU coatings. The ratio of NCO/OH groups ...
Mechanism of charge transport in castor oil-based polyurethane/carbon black composite (PU/CB)
(Elsevier B.V., 2012-01-15)
In order to identify and quantify the conduction mechanisms involved in the transport process, castor oil based polyurethane/carbon black composite (PU/CB) was introduced in a statistical model that reproduced the ac ...

Preparation of polyurethane monolithic resins and modification with a condensed tannin-yielding self-healing property
(2019-11-01)
Resins of polyurethane were prepared from vegetable oils (crambe and castor) and modified by adding green corrosion inhibitor (condensed tannin). The oils were characterized by gas chromatography with flame-ionization ...
Preparation and physicochemical characterization of drug loaded in castor oil-based polyurethane
(Springer, 2020-02-01)
Castor oil is an environmentally friendly alternative to hydrocarbon-based feedstocks for the synthesis of polyurethanes due to its major constituent, ricinoleic acid. This work aimed to obtain and characterize castor ...
Preparation and characterization of castor oil-based polyurethane/poly(o- methoxyaniline) blend film
(2007-07-15)
Blends made up of castor oil-based polyurethane (PU) and poly(o-methoxyaniline) (POMA) were obtained in the form of films by casting and characterized by FTIR, UV-Vis-NIR spectroscopy, and electrical conductivity measurements. ...
