molecular dynamics-assisted design of high temperature

Molecular Dynamics-Assisted Design of High Temperature

The blending model of three synthetic polyacrylamides (cationic, anionic, and nonionic) and poloxamers was first established, and then the interaction process between them was simulated by all-atom molecular dynamics. In the results, it was found that the hydrogen bonding between the amide groups on all polymers and the oxygen-

Molecular Dynamics-Assisted Design of High Temperature ... - MDPI

Polyacrylamide has promising applications in a wide variety of fields. However, conventional polyacrylamide is prone to hydrolysis and thermal degradation under high temperature conditions, resulting in a decrease in solution viscosity with increasing temperature, which limits its practical effect. Herein, combining molecular dynamics and practical experiments, we explored a facile and fast

The Thermal Gelation Behavior and Performance Evaluation of

The thermal gelation behavior of nonionic polyacrylamide (NPAM) and PEI was investigated, and sodium citrate (NaCit) was selected as a new retarder to prolong the gelation time. The gelation performance of NPAM/PEI gel system can be adjusted by varying NPAM or PEI concentration, and a quadratic model is developed by statistical analysis, which

frost heave mitigation of silt clay using nonionic polyacrylamide

Frost heave mitigation of silt clay using nonionic polyacrylamide

An increase in the nano-silica content decreased the average pore diameter. In addition, nano-silica filled the pores between particles of silt clay and blocked the migration tunnel of water. If the content of nano-silica reaches 2%, the frost heave ratio can be reduced from 8.8% to 5.3% (freezing for 35 h).

Rheology Properties of Underwater Cement Paste with Nonionic

In this article, underwater cement paste (UWP) was fabricated through using the high molecular nonionic polyacrylamide (PAM) as anti-washout admixtures (AWAs). The traditional coaxial rotary method was used to systematically investigate UWPs rheology parameters. A new B-HB model was successfully used for simulating the obtained shear stress versus shear rate diagram. The results showed that
