Research of the Dispersity of the Functional Sericite/Methylphenyl- Silicone Resin

Abstract

In order to improve the homogeneity and dispersity of the sericite in methylphenyl-silicone resin, the agglomerate state of the sericites was controlled effectively. The dispersive model of the sericite in methylphenyl-silicone resin was designed also. First, the modified sericite was prepared using hexadecyl trimethyl ammonium bromide as the intercalating agent. Then, functional sericite was incorporated into methylphenyl-silicone by terminal hydroxyl. The structure and dispersive performance of the hybrid polymers was charactered by analytical instruments. Scanning electron microscopy and Transmission electron microscope, Laser scanning confocal microscope and X-ray diffraction analysis showed that functional sericite was dispersed homogeneously in methylphenyl-silicone resin matrix. X-ray photoelectron spectroscopy analysis showed that the absorption peaks of the Si-OH band of methylphenyl-silicone resin were decreased and the Si-O-Si band was increased. This change evidently showed a significant role to enhance the reaction degree of the functional sericite in methylphenyl-silicone resin.

Atomic‐Layer‐Deposited Amorphous MoS2 for Durable and Flexible Li–O2 Batteries

“…The peak at ≈286.2 eV in C 1s spectrum is consistent with absorbed electrolyte (O–CH 3 ) (Figure A) . The weak peaks at ≈288.6 eV (Figure A), ≈534.4 eV and ≈532.1 eV (Figure D) correspond to the OCO bonds which may be associated with the degradation of electrolyte or dimethyl carbonate residues (used for rinsing electrodes to remove tetraethylene glycol dimethyl ether (TEGDME) before XPS characterization) . Moreover, O 2 crossover that cannot be effectively blocked in organic liquid electrolytes and volume change of Li metal during cycling may also give rise to the degradation of Li anode.…”
