In a previous work researchers found that fluorinated acrylate (PHFDA)/styrene (PSt)/ sulfonated styrene (S) copolymer can enhance the viscosity of carbon dioxide (CO2) by factors greater than 100 at concentrations of 5 wt %. To further improve the efficiency of this copolymer, we apply the dissipative particle dynamics (DPD) method to investigate the link between copolymer molecular structure and the solution rheology. Results show that sulfonated copolymer molecules combine with each other and create self-assembly structures, which greatly thicken liquid CO2. We conclude that we should increase the sulfonation degree on the premise of a reasonable solubility. Using a further dissolving experiment, we finally fix the mole fraction of PHFDA, PSt and S on 60%, 24% and 16%, respectively. We test the viscosity of the improved copolymer with rheometer, results show that it can increase the solution viscosity 180-fold relative to neat CO2 at 334K and 28 MPa with a concentration of 2.5 wt %.
