We focused on optimizing synthetic parameters based a Taguchi design to maximize polymer yield and evaluate the polymer-thickening ability in CO<sub>2</sub>.
Silicone polymer shows high performance for thickening supercritical carbon dioxide and has become a well-known target because it is inexpensive environmentally friendly. In this study, siloxane was synthesized by copolymerization reaction. The synthesis conditions of the silicone were optimized using Box-Behnken design, yield from process considered as an evaluation criterion in screening process. effect evaluated in-house-built ball viscometer with operation pressure not exceeding 30 MPa....
The low viscosity of pure liquid CO2 hindered the development fracturing technology. A modified silicone polymer was prepared as a thickener to investigate effect temperature, pressure, shear rate and content (wt.%) on apparent rheology thickened CO2. In addition, capacity evaluated with numerical simulation extended finite element. results displayed that an up 1.3 mPa·s at 303 K 18 MPa attained over using 3 wt.% Toluene 9 additives. Compared commercial linear polydimethylsiloxane, better...
Some drawbacks of the hydraulic fracturing technology included water pollution and reservoir destruction, hindered its development application in shale reservoirs. CO2 fluid is considered to be an excellent substitution conduct operation because cheapest, enhance gas production environment friendly. However, low viscosity high filtration property pure are viewed as a huge challenge develop technology. In this paper, we synthesize modified silicone thickener investigate effect different...
ABSTRACTIn comparison to hydraulic fracturing, CO2 fracturing technology is more efficient and effective in solving environmental problems caused by the process. However, low viscosity pure under high pressure hinders development of entire technology. Given that, a siloxane that can significantly improve liquid prepared excellent performance thicken silicone polymer shown. Polymerization occurs water conditions presents trend likely trigger reaction than ring-opening polymerization anhydrous...
Effectively improving the mechanical properties and thermal resistance of epoxy shape‐memory polymers (ESMPs) without affecting their performance is necessary to expand these in practical applications. In this article, modified multi‐walled carbon nanotubes (MWCNTs) were prepared used as efficient reinforcement for enhancing comprehensive ESMPs. Increases nearly 289% 444% impact strength 112% 184% tensile force obtained by adding only 0.1 1 wt% epoxy‐modified MWCNTs. The addition unmodified...
Abstract The grafting of a polymer can lead to the improvement and modification thus expand its applications. Grafting methods include solution in organic solvents, melt at high temperatures, light with radioactive sources. These have their advantages disadvantages. disadvantages waste treatment, consumption energy, so on. In this study, hydrothermal process which is called green approach, was developed prepare graft copolymers. effect various factors on degree investigated detail. © 2008...
Silicone shows an excellent performance of thickening CO2 and becomes a well-known thickener due to the low price environmentally friendly. Siloxane copolymers could be synthesized via copolymerization other reactions. Optimal preparation parameters were temperature 90°C, aminopropyltriethoxysilane-to-methyl triethoxysilane molar ratio 2:1, amount catalyst 0.09 g. The yield production coordinated well with predicted 83.72%. structure is analyzed by FTIR. Adding 3% w.t. 7.2 order magnitude...
