Cross-linked polymer nanocomposite networks coated nano sand light-weight proppants for hydraulic fracturing applications

Abstract

Three-dimensionally cross-linked polymer nanocomposite networks coated nano sand light-weight proppants (LWPs) were successfully prepared via ball-milling the macro sand and subsequently modifying the resultant nano sand with sequential polymer nanocomposite coating. The modified nano sand proppants had good sphericity and roundness. Thermal analyses showed that the samples can withstand up to 411 ℃. Moreover, the proppant samples’ specific gravity (S.G.) was 1.02–1.10 g/cm3 with excellent water dispersibility. Therefore, cross-linked polymer nanocomposite networks coated nano sand particles can act as potential candidates as water-carrying proppants for hydraulic fracturing operations.

Mechanical strength investigation of chemically reinforced sandy soil using organic copolymers for geotechnical engineering applications

“…If the copolymer concentration of the reinforced sand samples was high, the compressibility strengths were also found to be high [63]. This increase in the samples' mechanical strength is attributed to the addition of high-strength thermoplastic polymers to the sand and the successful cross-linking of copolymers with the sand surfaces [30,31,33,34,40,[45][46][47][48][49][50]55,56,60].…”

Sulfonated mesoporous polystyrene-1D multiwall carbon nanotube nanocomposite as potential adsorbent for efficient removal of xylene isomers from aqueous solution

“…Since there is a growing tendency to use adsorption as an effective tool for removing dissolved aromatic hydrocarbons, discovering new porous materials exhibiting very high adsorption capacity with rapid regeneration characteristics is inevitable. Moreover, numerous absorbent polymers or porous polymer-based systems are exploited in oil and gas [9,[43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] and other industries [54,[58][59][60][61][62][63][64][65] . Carbon nanostructures-based composite adsorbents are emerging as potential adsorbents for removing dissolved organic compounds from water solutions [66][67][68] .…”
