Synthetic Environmentally Friendly Castor Oil Based-Polyurethane with Carbon Black as a Microphase Separation Promoter

Biodegradation of Polyurethane Derived from Castor Oil

The aim of this research was to study the biodegradation of a polymer derived from castor oil, which is a renewable, natural material that is a practical alternative for the replacement of traditional polyurethane foams. Due to its molecular structure, which contains polyester segments derived from vegetable oil, the polymeric surface is susceptible to microorganism attack. This study tested th...

Characterization of Novel Castor Oil-Based Polyurethane Polymer Electrolytes

Castor oil-based polyurethane as a renewable resource polymer has been synthesized for application as a host in polymer electrolyte for electrochemical devices. The polyurethane was added with LiI and NaI in different wt% to form a film of polymer electrolytes. The films were characterized by using attenuated total reflectance-Fourier transform infrared spectroscopy, dynamic mechanical analysis...

Possibilities Of Using A New Graphite-Castor Oil Polyurethane Composite Electrode As An Amperometric Flow Detector

The performance of a new graphite castor oil polyurethane composite electrode is evaluated as an amperometric flow injection detector using hydroquinone (HQ) as a probe. HQ was determined in photographic developers with a minimum detectable net concentration of 100 μmol L-1, and 81 determinations h-1, after optimization of parameters such as the detection potential, sample loop volume, and carr...

Effect of Dates Extracts as Environmentally Friendly Corrosion Inhibitor for Carbon Steel in 1M HCl Solution

Inhibitory effect of extracts from three date varieties namely khalt (kha), Lassiane (La) and Tadmamt (Td)), and the mixture of date varieties as environmentally friendly corrosion inhibitor for carbon steel in 1M HCl is studied by means of electrochemical tests such as electrochemical impedance spectroscopy (EIS), and Tafel polarization. It's been obtained that in 1.0 M HCl solution the date e...
