A Comprehensive Study of Hydrolyzed Polyacrylamide

In this work, we comprehensively investigate the physical properties and performance of a molecular-weight series (3–20 × 10 6 g/mol) of partially hydrolyzed polyacrylamide (HPAM) in silicon anodes. We quantify the mechanical strength, electrolyte uptake, adhesion to silicon, copper, and carbon, as well as electrochemical performance and

New Nanohybrid Based on Hydrolyzed Polyacrylamide

The covalent bond between APTES-functionalized SiO 2 nanoparticles (nSiO 2-APTES), and the hydrolyzed polyacrylamide (HPAM) chain (MW ≈ 20.10 6 Da) was confirmed with high-resolution X-ray spectroscopy (XPS). Finally, the thermal properties of the nanohybrid were evaluated by using thermogravimetric analysis (TGA) and differential scanning

Influence of Hydrolyzed Polyacrylamide (HPAM) Molecular

The influence of the molecular weight (Mw) of hydrolyzed polyacrylamide (HPAM) on the cross-linking reaction of HPAM/Cr3+ and the transportation of HPAM/Cr3+ in microfractures is systematically studied using viscometry, ultraviolet–visible absorption spectrophotometry, and displacement experiment with a visual microfractured model. The results show that a high-Mw HPAM is advantageous to the

rheological properties of partially hydrolyzed

Rheological Properties of Partially Hydrolyzed

This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO2) nanoparticles (NPs). Novel aqueous HPAM-based SiO2 nanocomposites were formulated, and their rheological properties were investigated under different salinities, temperatures, and aging times.

Nanoparticles for Enhanced Oil Recovery: Influence of pH

New methods are continuously being evaluated for Enhanced Oil Recovery (EOR). Nanoparticle flooding is an intriguing new approach in which one of the main applications is microscopic diversion. Linked polymer solution (LPS) is a nanoparticle system that consists of partially hydrolyzed polyacrylamide (HPAM) cross-linked by aluminum(III). The source of aluminum is an aluminum citrate (AlCit
