ELECTROCHEMICAL DEPOSITION OF MAGNESIUM IN ETHEREAL GRIGNARD SALT SOLUTION WITH IONIC LIQUID ADDITIVE

The electrochemical deposition of magnesium was investigated in ethereal Grignard salt solution with tetraethylammonium bistrifluoro-methanesulfonimidate additive, using cyclic voltammetry, potentiostatic transients, and scanning electron microscope measurements. The voltammograms showed the presence of reduction and oxidation peaks associated with the deposition and dissolution of magnesium. From the analysis of the experimental current transients, it was shown that the magnesium deposition process was characterized as a three-dimensional nucleation. The deposited product obtained from potentiostatic reduction presented a generally uniform and dense film.

Compatibilizing effects and mechanism of compatibilization of LLDPE/PEO blends by EAA

The compatibilizing effects of the compatibilizer, ethylene-acrylic acid random copolymer (EAA), on linear low density polyethylene (LLDPE)/poly(ethylene oxide) (PEO) blends and the mechanism of compatibilization of the blends have been studied. Morphology and microstructures as characterized by SEM, DMA, DSC and IR show that EAA can act as an effective compatibilizer, and the mechanism of compatibilization is due to the compatibility of amorphous phases between EAA and LLDPE, and intermolecular interaction between the carboxylic groups in EAA. and the ethereal oxygens in PEG.
