Potential applications of poly(vinyl alcohol)-congo red aqueous solutions and hydrogels as liquids for hydraulic fracturing
The authors report on the viscoelastic characterization of guar hydrogels obtained through complexation reactions with borax ions. These gels are compared with hydrogels obtained from poly(vinyl alcohol) of different degree of hydrolysis through complexation reactions with congo red. The effect of t...
