Tribological study of castor oil with surface-modified CuO nanoparticles in boundary lubrication
Industrial Lubrication and Tribology, 2018Purpose The present work aims to formulate nanolubricants and improve antiwear, antifriction and extreme pressure (EP) performances of castor oil (CO) with surface-modified CuO nanoparticles as an additive in the boundary lubrication regime. Design/methodology/approach In this study, CuO nanoparticles are modified with a surfactant sodium dodecyl ...

Synthesis and properties of radiation modified thermally cured castor oil based polyurethanes
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2007Abstract Thermally cured polyurethanes were prepared from castor oil and hexamethylene diisocyanate (HMDI). Due to the long aliphatic chain of the castor oil component of polyurethane, thermal curing of castor oil based polyurethane (COPU) is limited by increasing polymer viscosity. To enhance further crosslinking, COPUs were exposed to doses up to 3.

STUDY OF CRYSTAL MORPHOLOGIES OF HYDROGENATED CASTOR OIL AS A RHEOLOGY MODIFIER
2012Hydrogenated castor oil (HCO) crystals as a rheology modifier have been widely used in paints, cosmetics and household products. In this thesis, we are interested in the effect of crystal morphology on the suspension rheology of products. Three major types of micron-sized crystal morphologies have been observed: fiber, rosette and irregular crystal ...
