摘要

Polyethylene glycol (PEG) displayed an amazing properties when mixed with other polymers orinorganic materials. Polymers of different types (organic, inorganic or hybrid) and a variety ofinorganic materials have been blended and showed interesting properties. So that, a new experimentaldesign of PEG / MCM-41composites has been prepared using different loading from PEG. MCM-41as one of the most important mesoporous material has been used as support material. The preparationprocess for the new composites has been carried out using a simple dissolution method. Freshlyprepared MCM-41 has been investigated by simple characterisation tools. The obtained structure of thenew composites was promoted by various characterization techniques. which including: Fouriertransform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field-emission scanning electronmicroscopy (FE-SEM), and thermal analyses have been used as characterization tools. Moreover, theelectrical properties were measured using electrical conductivity measurements. SEM images showednearly the same globular grain in both cases for pure MCM-41 and PEG / MCM-41(10%) composite.Whereas PEG / MCM-41(30%) composite showed different feature. The increasing the PEG percentagetill 20 % was accompanied by a continuous decrease of the WL %.
