High solids content film-forming poly[styrene-co-(n-butyl acrylate)] [poly(Sty-co-BuA)] latexes armored with Laponite clay platelets have been synthesized by soap-free emulsion copolymerization of styrene and n-butyl acrylate. The polymerizations were performed in batch in the presence of Laponite and a methyl ether acrylate-terminated poly(ethylene glycol) macromonomer in order to promote poly...

SHG measurements on a highly transparent clay film ion-exchanged with chiral metal complexes revealed that the mono-molecular layer of the chiral complexes in an interlayer space acquired a non-centrosymmetric character.

A method of clay mineral sample preparation for electron microprobe analysis has been developed in which a film of clay plus 10-12 wt. % colloidal graphite is deposited on a porous ceramic disc using a specially designed suction device. Correction procedures are used to obtain quantitative elemental analyses representing the average chemical composition of the prepared sample. A statistical tec...

H. F. Wang, J. J. Lu, K. F. Chen, H. L. Duan, Wuhan Textile University, Wuhan, China A new method to treat four solid wastes of sodium silicate used sands, dewatered municipal sludge, clay sands sludge and waste polyethylene, was discussed. About wt/ 50 % sodium silicate used sands and wt/ 50 % dewatered sludge were mixed, and then cured by microwave with a certain thickness film of clay sands ...

Organically modified clay was used as reinforcement for HDPE using maleated polyethylene (PEMA) as a compatibilizer. The effect of compatibilizer concentration on the orientation of various structural features in the polymer-layered silicate nanocomposite (PLSN) system was studied using two-dimensional (2D) small angle X-ray scattering (SAXS) and 2D wide-angle X-ray scattering (WAXS). The dispe...

No. DiMa0147 Structure of a Functionalized Oxacarbocyanine / Saponite Clay Nanofilm E. DiMasi (BNL), R. Ras and R. Schoonheydt (K. Univ. Leuven, BELGIUM) Beamline(s): X22A Introduction: Nanoscale functionalized organic films are of technological importance, for example in the case of dye molecules, where assembly into well ordered thin films produces desirable optical properties for miniaturize...

Poly(vinyl alcohol) (PVA)-montmorillonite (MMT) clay nanocomposite films up to 10 wt% clay concentration were synthesized by aqueous solution grown technique. The relative complex dielectric function, alternating current electrical conductivity, electric modulus and impedance properties of these organic-inorganic nanocomposites were investigated in the frequency range from 20 Hz to 1 MHz at amb...

Beltanelloides sorichevae Sokolov, 1965 is one of these simple forms. This taxon was originally described from sediments of the Upper Vendian of the European Platform, in the White Sea region. Organisms were typically preserved as negative, rounded impressions with thin, irregular concentric wrinkles on the periphery of an organic film. Remains lay in beds of massive, structureless clay. Such i...
