Organic Modification Of Montmorillonite With Low Molecular Weight Polyethylene Glycols And İts Use İn Polyurethane Nanocomposite Foams
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2010-10-20)
This paper deals with the preparation of organoclays by intercalating poly(ethylene glycol) molecules (PEG) between Na montmorillonite (Na-MMT) layers in a clay-water suspension system. X-ray diffraction (XRD) results of ...
The Modification Of Na-Montmorillonite By Salts Of Fatty Acids: An Easy İntercalation Process
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2010-11-20)
The organic modification of Na-montmorillonite (Na-MMT) clay by a reaction with the sodium salts of octadecanoic acid (SOD) and dodecanoic acid (SDD) was studied for the production of effectively intercalated and organophilic ...
Organic Phase Change Materials And Their Textile Applications: An Overview
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2012-07-20)
An organic phase change material (PCM) possesses the ability to absorb and release large quantity of latent heat during a phase change process over a certain temperature range. The use of PCMs in energy storage and thermal ...
