Abstract

We fabricated polyacrylamide (PAM)/polyethylene mine (PEI) gels doped with graphene oxide (GO). Their shape and residences had been systematically studied through X-ray diffraction (XRD), Fourier transition infrared spectroscopy (FT-IR), Raman spectroscopy, scanning electron microscopy (SEM), differential scanning calorimeter (DSC), and rheological experiments been appreciably researched. As a result, graphene oxide (GO) Nano sheets had been proven to facilitate the cross-linking response among the principle energetic element (PAM) and the cross-linker (PEI), functioning as multi-useful cross-linkers and powerful reinforcing Nano-fillers. I was. By growing the content material of the principle energetic element and the cross-linking agent, we’ve got efficiently advanced the power of the gel. Thanks to the advanced third-dimensional honeycomb shape with controllable pore size, GO should efficiently song the power and gelation time to show off susceptible gel residences. DSC showed that the PAM/PEI/GO gel has true thermal balance and does now no longer dehydrate above 170 °C. This painting gives theoretical guide for in addition optimization of polyacrylamide gels utilized in ultra-deep and excessive temperature reservoirs for water control.
