Cross-linked poly(tetrahydrofuran) as promising sorbent for organic solvent/oil spill

Natural rubber/reduced-graphene oxide composite materials: Morphological and oil adsorption properties for treatment of oil spills

“…Since the industrial revolution, the demand for petroleum products has remarkably increased, thereby leading to an increased risk and frequencies of oil leakages through the extraction, transportation, transfer, and storage of oil. Oil spills in the natural environment cause catastrophic effects on the environment and ecosystem [1], [2], [3]. Various methods have been developed to solve this serious problem, such as physical [4], [5], [6], [7], chemical [8], [9], [10], and biological [11], [12], [13] approaches.…”

The electrospinning of the copolymer of styrene and butyl acrylate for its application as oil absorbent

“…Zhang et al (2015) chose carbonyl iron powders as magnetic material to prepare magnetic poly(styrene–divinylbenzene) monoliths with porous structure and lipophilicity through direct molding and controlled polymerization, and they found that the monoliths had an oil intake capacity of approximately 23 times its own weight. Yati et al (2016) prepared an oil absorbent with a cross-linked 3-dimensional network via the condensation of poly(tetrahydrofuran) with tris[3-(trimethoxysilyl)propyl] isocyanurate, and they found that the absorbent had a high and fast swelling capacity in various oils. Up to now, some achievements have been made in the field of absorbents preparation.…”

Preparation of biphenyl‐bridged, crosslinked polyalkoxysilanes: Determination of oil/organic solvent absorption features

“…When the swelling properties of the biphenyl‐bridged, crosslinked polyalkoxysilanes were compared with the swelling properties of other crosslinked polymers in the literature (i.e., a semi‐interpenetrating network based on polydimethylsiloxane in DCM = 120%, methacrylate based crosslinked polymer in toluene = 360%, crosslinked polyorthosilicates in DCM = 310%, polyalkoxysilane sorbents in benzene = 520%, PDMS sponges in chloroform = 1100%, crosslinked polyalkoxysilanes in DCM = 876%, PTHF‐based sorbents in DCM = 1800%, crosslinked aminopolysiloxanes in DCM = 700%, conjugated microporous polymers in DCM = 1240%, crosslinked polyesters in chloroform = 800% and phenylene‐bridged polyalkoxysilanes in THF = 670%). Our results for the crosslinked biphenyl based polyalkoxysilanes were clearly competitive (at this level, 1 g of biphenyl‐bridged polyalkoxysilane absorbed almost 15 g of DCM), and the synthesized polymers could be used as absorbent materials for organic solvents and oils.…”

“…When oil leaks into water or other parts of the environment, it spreads quickly, negatively affecting living creatures and our habitat . To clean such oil and organic solvent pollutions from water surfaces and the environment, a wide range of synthetic and inorganic materials are used, including perlite, clay, diatomite, calcium carbonate powder, and zeolite for inorganic materials and polydimethylsiloxane (PDMS)‐coated cotton; carbon nanotube sponges; polyester sorbents; poly(propylene glycol)‐based sorbents; poly(ethylene glycol) gels; cyclodextrin‐based polymers; silica aerogels; polypropylene sorbents; tetraethyl orthosilicate (TEOS)‐based sorbents; crosslinked methacrylate materials; tetraethylorthocarbonate‐based crosslinked polymers; alkoxysilane‐based organogels; polytetrahydrofuran (PTHF) sorbents; and alkyl and aromatic bridged polysilsesquioxanes …”
