Effects of silica nanoparticle on the solution properties of hydrophobically associating polymer based on acrylamide and beta-cyclodextrin
Synthesis of a novel beta-cyclodextrin-functionalized hydrophobically associating polyacrylamide named ASM was carried out using acrylamide (AM), cetyl dimethyl allyl ammonium bromide (SD-16) and modified beta-cyclodextrin (M-beta-CD) via free-radical copolymerization. Effective characterization methods, including FT-IR, H-1 NMR and TGA, were adopted to evaluate ASM. Influences of SiO2 nanoparticle (nanoSiO(2)) on ASM solution properties were evaluated. The results showed that the addition of nano-SiO2 significantly increased the temperature resistance, salt tolerance and shear resistance of the ASM solution. It was found that ASM/SiO2 composite had 1.5 times higher viscosity than ASM in the range of 25 -90 degrees C. The FT-IR data confirmed that the formation of hydrogen bond between silanol groups at surface of nano-SiO2 and amide group, hydroxyl group of M-beta-CD in ASM molecule contributed to the improved performance. What s more, viscoelastic test indicated that nano-SiO2 remarkably facilitated the crosslinks among polymer molecules and enhanced the elasticity of ASM/SiO2 composite. Based on the enhanced oil recovery tests, the oil recovery could remarkably enhance 10.08% for composite versus only 6.56% for ASM. (C) 2019 Elsevier B.V. All rights reserved.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 766-96-1. Computed Properties of C8H5Br.
