Preparation and application of melamine cross-linked poly ammonium as shale inhibitor

In this paper, a series of poly ammonium shale inhibitors were prepared from diethylamine, epichlorohydrin, and melamine (DEM) and their inhibition to shale were evaluated by bentonite linear expansion test, anti-swelling experiments, and mud ball experiments. Additionally, other properties of drilling fluid treated by poly ammonium were evaluated. Anti-swelling results showed...

Preparation and electrochemical property of CMC/MWCNT composite using ionic liquid as solvent

Carboxymethyl cellulose sodium (CMC)/multi-walled carbon nanotube (MWCNT) composite was prepared by dissolving CMC with ionic liquid as solvent. The microstructure and electrochemical properties of CMC/MWCNTs were studied using field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD) system and...
