Abstract

Oil–water separation using polythiophene coated cellulose sponge and fabric.

Current Status of Cellulosic and Nanocellulosic Materials for Oil Spill Cleanup

“…Further strategies to increase hydrophobicity is the incorporation of inorganics (TiO 2 layers [ 73 ] or NPs [ 74 , 75 ]) Cu-NPs [ 76 ], Ag-NPs [ 77 ], Al 2 O 3 -NPs, surfactants (cetyltrimethylammonium chloride, CTAC [ 78 ], SDS [ 79 ], stearic acid (SA) [ 71 , 80 ], oleic acid [ 56 , 81 ], epoxidized soybean oil (ESBO) [ 82 ]) or other types of grafting molecules (polydopamine PDA and octadecylamine ODA [ 83 , 84 ], poly( N , N -dimethylamino-2-ethyl methacrylate) PDMAEMA [ 85 ], polythiophene [ 86 ], acid chlorides [ 87 , 88 ], by carboxymethylation [ 60 ] or polymers [ 89 , 90 ]). As with the materials formed by carbonization, there cannot be a general rule deduced to state which hydrophobization method is the best in order to achieve the most beneficial material properties.…”

“…In this section a brief overview about alternative preparation methods is given, which cannot be attributed to the previous techniques, but still play a role for preparation of porous lignocellulosic materials. In the easiest case, porous cellulose materials can be found in nature, like cellulose sponges typically used as kitchen wipes, but those have comparable low-specific surfaces [ 86 ]. The incorporation of chemical foaming agents (e.g., p-toluenesulfonyl hydrazide) or physical foaming agents (e.g., Na 2 SO 4 ) into cellulose solutions were reported for the preparation of aerogels [ 59 ].…”

“…A superhydrophobic surface designed by less-expensive, biodegradable and environmentally friendly route for oil/water separation with fabrics has drawn increasing interest across the scientific community [ 86 , 197 , 198 ]. However, the applications of hydrophobic surfaces are still hampered by lengthy preparation procedures and high-cost manufacture.…”

In-Situ Synthesis of Hydrophobic Polyurethane Ternary Composite Induced by Hydroxyethyl Cellulose through a Green Method for Efficient Oil Removal

“…Moreover, the hydrophobic composite that had absorbed oil could be regenerated easily by squeezing and recycling.Polymers 2020, 12, 509 2 of 12 subsequent processing procedures. Therefore, researchers are trying to explore better new oil-water separation materials.Recently, some new and efficient absorbent materials such as photoresponsive materials [15], carbon nanotubes (CNTs) [16], graphene-based materials [17][18][19], nanocellulose materials [20][21][22][23][24], and PU-based absorbents have attracted significant attention in oil-water separation applications [25,26]. PU sponge is considered to be one of the best absorbent methods because of its low density, high porosity, and high elasticity [27][28][29].…”

Mechanochemical synthesis and composite properties polyanіline/cellulosе

“…Висока гідрофільність Цел сприяє високій адсорбції води, однак для кристалічної Цел вона є нижчою стосовно аморфної Цел, оскільки для води доступна лише поверхня кристалітів [7]. Гідрофільність Цел робить її придатною для поєднання з багатьма неелектропровідними полімерами [10][11][12][13][14] та ЕПП, як-от поліпіролом [15][16][17]; політіофеном [18,19]; полі(п-феніленетиленом) [20]; поліаніліном [20][21][22][23][24][25] та ін. Наявність на поверхні фібрил Цел -О-Н груп (див.…”
