Graphene Modified Porous Material (Blocky Graphene Modified Sponge)


Product Description

MstnLand's graphene modified sponge is a kind of 3D graphene modified porous material which combines hydrophobic and oleophilic graphene with common commercial porous sponge. By incorporating graphene into a sponge-like structure, the resulting graphene modified sponge inherits the excellent properties of graphene and gains additional functionalities. The graphene component enhances the mechanical strength, electrical conductivity, and overall performance of the sponge material. So that it has the high mechanical strength of graphene, high electrical conductivity, high thermal conductivity, excellent hydrophobicity, but also has the characteristics of sponge high resilience, porous structure, large porosity and large surface area. These characteristics make it suitable for a variety of applications, and has great performance advantages in adsorption, filtration, and catalytic applications. The graphene modified sponge has a high adsorption capacity for various water pollutants such as dyes, oils and other organic solvents, and it’s capable of absorbing various oil and organic solvent pollutants equivalent to 120 times its own weight.

MstnLand's graphene modified sponges can be used to deal with oil spills during oil extraction, refining and transportation, as well as organic solvent pollution used and emitted in the chemical industry. Using graphene modified sponge instead of oil absorbing felt to deal with oil spill pollution at sea, it can still float on the water after absorbing oil, easy to salvage and recycle, and can be reused more than thousands of times. When the graphene modified sponge reaches the absorption saturation state, it can be used repeatedly after physical extrusion treatment, and can keep the structure and performance without significant change and degradation.

Due to different application scenarios and technical specifications, MstnLand's graphene modified sponges can be customized according to customer requirements in various shapes, sizes and specifications, such as graphene sponge balls, graphene sponge blocks, graphene sponge boards, graphene sponge cakes, graphene sponge filters, etc.


As shown in the figure above, add a simulated sea water containing 3.5% NaCl and pour 10 mL crude oil into the tank. A graphene modified sponge is held with tweezers and the oil on the water surface is absorbed back and forth. Under the action of the sponges' lipophilic and capillary forces, the crude oil from the water surface quickly penetrates into the sponges' pores. With the recovery process, the oil storage space of sponge gradually decreases, and the oil absorption rate decreases compared with the beginning. After 90s, most of the oil is recovered, and the sponge can continue to float on the water surface, which is conducive to salvage and recovery.


The water bottom of the beaker is trichloromethane stained with Sudan Red III. Dip the graphene modified sponge into the water bottom, and the trichloromethane is immediately adsorbed without absorbing water. It can be seen that in addition to oil recovery on the water surface, graphene modified oil absorbing sponge also has good selective adsorption for underwater oil or organic solvent leakage, and can be applied in the field of underwater oil and water separation. Sponges are good at oil philicity and hydrophobicity, and have strong selective absorption for heterogeneous oil-water mixing systems. They have great advantages in waters where large mechanical recovery equipment is difficult to operate, such as shoals and riverbanks.

The above is the electron microscope scanning of the corresponding microstructure of blank sponge and graphene-supported sponge magnified 500 times (left) and 3000 times (right) respectively. Figure a and b show that the skeleton of blank melamine sponge is smooth and interwoven, forming multistage micropore structure with pore size ranging from tens to hundreds of microns. Therefore, oil or organic solvents can freely pass through the internal pores; The cross-linked skeleton structure of the sponge can also effectively support the weight of the adsorbed oil, giving the sponge a larger oil absorption capacity. According to the surface wetting theory, the material surface wettability is related to surface roughness and chemical properties. Because the blank sponge skeleton surface is smooth and flat, and contains a large number of hydrophilic groups, the oil-water separation selectivity is poor. As can be seen in Figure c and d, a large number of clumped and irregularly distributed graphene coatings appeared on the surface of the skeleton structure of the graphene loaded sponge. After local amplification, it could be clearly seen that there were crumpled protrusions with micro or nano size attached to the pore wall, which greatly increased the roughness of the sponge.
