  • Does pH affect water uptake of poly(Aam)-co-poly (AAC) hydrogels?
  • Figure 8. Influence of pH on the water uptake of the poly (AAm)-co-poly (AAc) hydrogels. From the plot, it was obviously observed a gradual increase in swelling ratios from pH 2.2–7.0, and then a sharp transition is observed from pH 7.0–10.0 with a slight decrease in water uptake.
  • How is free radical copolymerization of PAAM hydrogels carried out?
  • After nitrogen bubbling for 15 min, free radical copolymerization of hydrogels was carried in glass tubes of 10 mm inner diameter at room temperature for 2 h, using APS and TEMED as redox initiator. Subsequently, the crosslinking of PAAm hydrogels was carried out by BIS.
  • What is a hydrogel synthesis based on poly(acrylic acid) and copolymers?
  • The present work focuses on the hydrogel synthesis of poly (acrylamide) and copolymers based on poly (acrylic acid) at various concentrations, N, N ′-methylene bisacrylamide was used as crosslinker. The swelling properties of the hydrogels, in different solutions (water, NaCl) and different pH were systematically studied.
  • Which polymer is used as a rheological thickener?
  • Poly (acrylic acid), was chosen as a thickener to study the rheological behavior of copolymer hydrogels, PAAc polymers as an anionic hydrogel are widely used to improve the rheological properties of thickening systems.
