Composite Fibrous Membranes

In this study, polyacrylonitrile (PAN) electrospun fibrous membranes were manufactured and applied for oil spill cleanup. Two kinds of composite fibrous membranes composed of PAN electrospun fibrous membranes and polyethylene/polyethylene terephthalate (PE/PET) core-shell fiber nonwoven fabric were fabricated. The fibrous structure, mechanical properties and surface wettability for water and oil, as well as oil absorption capacities and dynamic oil retention of the membranes, were investigated in detail. The addition of nonwoven fabric significantly enhanced the tensile strength of the PAN fibrous membranes. The oil absorption mechanisms of different membranes were studied as well. The sandwich structure composite fibrous membranes exhibited excellent mechanical property and oil absorption capacity, making it a promising candidate for treatment of oily wastewater.

Purpose The most widely recycled plastic in the world is recycled polyethylene terephthalate (rPET). To minimize the environmental related issues associated with synthetic fibers, several researchers have explored the potential use of recycled polyester fibers in developing various technical textile products. This study aims to develop needle-punched nonwoven fabrics from recycled polyester fibers and investigate its suitability in oil spill cleanup process. Design/methodology/approach According to Box and Behnken factorial design, 15 different needle-punched nonwoven fabrics from recycled polyester fibers were prepared by changing the parameters, namely, needle punch density, needle penetration depth and fabric areal weight. Several featured parameters such as oil sorption, oil retention, oil sorption kinetics, wettability and reusability performance were systematically elucidated. Findings The maximum oil sorption of recycled nonwoven polyester is found to be 24.85 g/g and 20.58 g/g for crude oil and vegetable oil, respectively. The oil retention is about 93%–96% in case of crude oil, whereas 87%–91% in case of vegetable oil. Recycled polyester nonwoven possesses good hydrophobic–oleophilic properties with static contact angle of 138° against water, whereas 0° against crude oil and vegetable oil. The reusability test results indicate that recycled polyester nonwoven fabric can be used several times because of its reusability features. Originality/value There is no detailed study on the oil sorption features of needle-punched nonwoven fabrics developed from recycled polyester fibers. This study is expected to help in developing fabrics for oil spill cleanups.

PMMA-BMA oil absorption resin was prepared by dispersion polymerization. Oil absorption properties were adjusted by changing the monomer ratio, content of initiator and crosslinking agent. Absorption capacity of porous material, which PMMA-BMA oil absorption resin adhesive in the polyurethane surface, was also investigated. The experimental results show that the best oil absorption ratio of PMMA-BMA copolymer resin was obtained when the MMA/BMA mole ratio was1:1.5, and the initiator and crosslinking agent was 0.4% and 0.35% of the copolymer resin respectively. The porous material was fabricated using the porous polyurethane sponge dipped in the liquid copolymer resin. The porous material resin can be reused since its low oil retention rate, and it can be used as absorption container of oil vapor.

Replication Method

Ceramic foam are a class of high porosity materials that are used for various applications. In this study, foam ceramic porcelain powder was produced by using polymeric sponge replication method at different solid content ranging from 30 to 50 wt. %. Properties of ceramic foam was characterized for porosity and density. Ceramic foam then grafted with methyltriethoxysilane (MTMS) at different concentration ranging from 0 to 9.0% v/v to determine hydrophobic effect and oil absorption capacity. From the results, it was found that the density of ceramic foam increased while porosity was decreased with increasing solid contents. It is clearly seen that, MTMS grafting contribute to hydrophobic effect of ceramic foam which enable repelling of water. The amount of oil absorbed by ceramic was found increased by increasing concentration of MTMS for all solid contents. As conclusion, MTMS give significant effects on hyrdophobic ceramic foam and produce good absorption capacity. The lower solid content produced better oil absorption compared to higher solid content due to presence of higher porosity.

Oil Spill Cleanup

In the last decade, a continuous increasing research activity is focused on the surface modification of natural porous materials for the efficient removal of oil contaminants from water. A continuous in-situ oil/water separation technique for oil spill cleanup had been designed using surface modified Irind mine pumice as a sorbent. Irind mine pumice is an aluminosilicate rock, with well-developed porosity, mechanical strength, high buoyancy, chemically inert and eco-friendly, therefore it must exhibit certain water-and oil absorption capacities. The modified pumice absorbs a broad variety of oils and organic solvents with high oil absorption capacity and negligible water take-up at both static and dynamic conditions. Irind mine pumice have been used with grain sizes ranging from 2.5 ... 5.0 mm. Oligomethylhydride siloxane is used as a modifier.

The aim of this paper is the synthesis and characterization of a composite silicone foam filled with expanded graphite (EG) for oil spill recovery applications. The EG foams were obtained using a foaming slurry consisting of a mixture of siloxane compounds as the matrix with an EG filler. The effect of the filler content’s performance on an innovative composite silicone-based foam was investigated. All the obtained samples exhibited an open cell morphology. Each foam was evaluated in four commonly used oils (kerosene, pump oil, naphtha and crude oil). Additionally, kinetics was studied in order to investigate the physical, chemical and mass transport mechanisms that act during the absorption phenomenon and uptake evolution of the contaminants. Foam filled with 3% of EG exhibited the highest absorption capacity, particularly with light oils kerosene and virgin naphtha (854 and 1016 wt.%, respectively). Furthermore, the kinetic study showed that pseudo-second order mechanisms better fitted the composite absorption performances, suggesting that the oil sorption into EG filled polydimethylsiloxane (PDMS) foams could be related to chemisorption mechanism. The results evidenced a good oil sorption capability and water/oil selectivity indicating this class of materials as a potentially applicable material for oil spill remediation.

Oil Spill Cleanup

In this research, the researchers study the fabrication of oil absorption, hydrophobic polyurethane (PU) sponge for application in an oil-spill cleanup model. Virgin PU is initially hydrophilic. PU is made hydrophobic by incorporating hydrophobic silica aerogel (SA) into PU 3D porous structure by stirring method and UV-treatment method. UV-irradiation promotes the attachment of SA onto the PU surface. Varying UV irradiation time and concentration of SA is done to attain an optimal attachment of SA on PU. Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), contact angle measurements (CA) are used to determine the adhesion of SA on PU. The loadings of SA with and without UV-treatment are compared. Results show that SA-PU with UV-treatment has more loading of SA than SA-PU without treatment. FT-IR spectra and SEM micrographs verify the results. Moreover, the SA-PU is tested for oil absorption to simulate oil-spill cleanup. The findings show fast (less than 3 seconds), recoverable oil-spills cleanup with simple method of preparation. In addition, SA-PU with UV treatment has higher absorption rate and %absorption efficiency when compared to original PU and SA-PU without UV treatment.
