Abstract:The addition of nanoparticles
has been presented as an alternative
approach to counteract the degradation of polymeric solutions for
enhanced oil recovery. In this context, a nanohybrid (NH34) of partially
hydrolyzed polyacrylamide (MW ∼12 MDa) and nanosilica modified
with 2% 3-aminopropyltriethoxysilane (nSiO
2
-APTES) was
synthesized and evaluated. NH34 was characterized by using dynamic
light scattering, Fourier-transform infrared spectroscopy, and thermogravimetric
analysis. Fluid-fl… Show more
