Conducting polymers, because of their special properties, are used to introduce conductive polymeric composites. Also, clays have recently been used for preparation of polymer composites with enhanced mechanical and thermal properties. The aim of this work is to study the synergetic effect of the co-presence of conducting polyaniline and montmorillonite in the polyethylene matrix. Polyethylene ...

Particles of Cobalt ferrite, CoFe2O4-, were coated with polyaniline (PANI) sulphate and phosphate during in-situ polymerization of aniline in an aqueous solution of sulfuric and phosphoric acid. The PANI-ferrite composites were characterized by Fourier transform infrared (FTIR) spectroscopy. Structures and morphology of products were studied by X-Ray Diffraction (XRD) and Scanning Electron Micr...

The understanding and control of early hydration of tricalcium silicate (C₃S) is of great importance to cement science and concrete technology. However, traditional characterization methods are incapable of providing morphological and spectroscopic information about in situ hydration at the nanoscale. Using soft X-ray spectromicroscopy, we report the changes in morphology and molecular structur...

A method has been developed to investigate the extent of polymer cross-linking that results following in situ photopolymerization of an acrylate-functionalized phospholipid assembly adsorbed onto a stabilized, membrane-mimetic film produced from a polyelectrolyte multilayer (PEM) on polytetrafluoroethylene (PTFE) grafts. The acrylate phospholipid monomer was synthesized, prepared as a unilamell...

in recent years many research works have been carried out on anti-corrosive nanocomposites coatings containing mineral reinforcements. the most important criteria in these attempts are polymerization method and the type of matrix and reinforcement of nanocomposites. in this regard, the physical and mechanical properties of the polymers in which a small amount of filler is used can be improved. ...

QIAN ZHAO: CO2-mediated formation of polymer/clay nanocomposites (Under the direction of Edward T. Samulski) In this thesis, the feasibility of scCO2 as both a processing medium and a polymerization medium for preparation of polymer/clay nanocomposites has been explored, with the first part discussing a CO2-mediated intercalation of poly(ethylene oxide) (PEO) in clay. It has been shown that CO2...

Polyacrylamide gel (PAG) dosimeters show considerable promise as three-dimensional dosimeters for the verification of complex dose distributions associated with conformal therapy. However, the potential of PAG dosimeters has not yet been borne out in clinical practice and it is apparent that basic investigations of these dosimeters are still required. The polymerization reactions in PAG dosimet...
