All polymers were purchased from Sigma-Aldrich. The structures of the selected polymers/co-polymers are presented in Fig. 1.The PAM solution was prepared using an overall composition of 1% (w/v) 10g concentration in 1000 ml beakers containing formation water with moderate salinity of 43,280 ppm and mixed with electric stirrer for 3 h.

Polyacrylamide degradation and its implications
Pei, Y., et al. Investigation of the degradation and stability of acrylamide-based polymers in acid solution: Functional monomer modified polyacrylamide. Petroleum 2 , 399–407 (2016). Article
This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO 2) nanoparticles (NPs).Novel aqueous HPAM-based SiO 2 nanocomposites were formulated, and their rheological properties were investigated under different salinities, temperatures, and aging times.
Plastics—Villain or Hero? Polymers and Recycled Polymers
Reductant: The CH 4, CO, H 2 and the char produced during the pyrolysis of the plastics can replace the coal-based coke as a reducing agent in blast furnace applications. Binder: Virgin thermoset polymers and inorganic silicones are adhesives and adhesion promotors (coupling agents).

Phototherapy can be used in two completely different but complementary therapeutic applications. While low level laser (or light) therapy (LLLT) uses red or near-infrared light alone to reduce inflammation, pain and stimulate tissue repair and regeneration, photodynamic therapy (PDT) uses the combination of light plus non-toxic dyes (called photosensitizers) to produce reactive oxygen species
- What is polyacrylamide used for?
- 1. Introduction Polyacrylamide (PAM) is widely used in various industries, such as wastewater treatment; oil-displacing; paper making; textile printing and dyeing; dredging; and cosmetics . It is mainly polymerized by acrylamide (AM) and the molecular weight can reach 1.5 million to 20 million.
- Are cationic polyacrylamide copolymers bad for the environment?
- Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
