Mercury capture with an inverse vulcanized polymer formed from garlic oil, a bioderived comonomer

Inverse vulcanised sulfur polymer nanoparticles prepared by antisolvent precipitation

“…Ternary systems or copolymer blends are commonly used in inverse vulcanisation to increase the reactivity of monomers or adjust the physicochemical properties of nal products. 9,36 Additionally, the cost and sustainability of the chemicals were also considered in this synthesis, in which not only elemental sulfur but also DCPD were industrial byproducts, and perillyl alcohol is a natural terpene. Fully cured poly(S-dicyclopentadiene) (poly(S-DCPD)) is crosslinked sulfur polymer, which is insoluble in solvents.…”

“…13 Not only performed better than same component bulk polysulde, in mercury uptake application, these novel nanoparticles were also comparable to other polysuldes synthesized by other crosslinkers, such as poly (S-r-canola) (1.81 mg g À1 ), 38 poly (S-rrice bran) (1.92 mg g À1 ), 38 poly(S-r-castor) (2.01 mg g À1 ), 38 and poly(sulfur-GOB-DCPD) (1.60 mg g À1 C 0 ¼ 20 ppm). 9 Admittedly, some inversed vulcanised polymer were reported with higher mercury uptake capacity than that of nanoparticles, 16,28 the relatively simple preparation processing (with no auxiliary materials) and higher productivity were signicant advantages of inverse vulcanised polymer nanoparticles. Finally, the efficiency of the sorbent to remove mercury in more realistic conditions was studied.…”

“…1,3-diisopropenylbenzene (DIB) was the rst crosslinker to be explored in inverse vulcanisation, and the product, poly(S-DIB), was a chemically stable and processable copolymer, which could be used in cathodes for Li-S batteries. Subsequently to this discovery, more economical and more sustainable inverse vulcanisation crosslinkers have been studied in order to maximise the advantage of the low cost and potential sustainability of their combination with sulfur waste, such as limonene, 7 dicyclopentadiene (DCPD), 8 diallyl disul-de, [9][10][11] divinylbenzenes (DVB), 12 perillyl alcohol (PA), 13 ethylidene norbornene (ENB), 14 and ethylene glycol dimethacrylate (EGDMA). 15,16 Meanwhile, a variety of corresponding applications, such as IR optics, 4,17,18 Li-S batteries, 4,12,19 construction materials, 4 antimicrobial materials, 20,21 controlled-release fertilisers, 22 adhesives, 11 and mercury capture, [7][8][9][23][24][25] were discovered due to these new materials' special properties.…”

Polysulfide Synthesis Using Waste Cooking Palm Oil via Inverse Vulcanization

“…Now vegetable oils are also applied to synthesize inverse vulcanized polysulfides. Canola [21][22][23], soybean [10], castor oil and rice bran oil [24], linseed and olive oil [3], garlic oil [25], etc. have been employed till now to produce inverse vulcanized polysulfides.…”
