“…Namely, the introduction of oxygen-rich groups onto carbon-based material (carboxyl, carbonyl, lactonic) via acid/based treatment enables the design of a surface architecture which is capable of creating efficient chemical and physical bonds with a polymer matrix. 24,25 These groups are anchors for the establishing of intermolecular interactions that allow the change of load transfer from the polymer matrix to the reinforcement, which results in a better response to the applied force and thus higher mechanical integrity of the composites. 3,20 Change of E follows a similar trend as tensile strength, i.e.…”

Two types of polymer waste materials, poly(ethylene terephthalate) (PET) and polycarbonate based Colombian Resin (CR-39), were used for the designing of fully recycled composite materials. Waste PET was employed for the synthesis of thermoset unsaturated polyester resin (UPR), while CR-39 was used as reinforcement in the UPR matrix. Prior to mixing, CR-39 particles were subjected to oxidation and chemical activation using acids/base and ethanol amine, respectively. The effect of the modifier type and variable loading of the activated CR-39 particles on mechanical and dynamic-mechanical properties of the corresponding composites was investigated. The greatest improvement in the tensile and flexural strength of UPR resin was achieved with the composite containing 0.5 wt% of amine activated filler particles, 96.0% and 62.2%, respectively. The Arrhenius equation was used to calculate the activation energy for glass transition from dynamic mechanical properties measured at various frequencies. The activation energy of the main transition for UPR resin and composites were calculated to be 173 and 350 kJ·mol−1 indicating that reinforcement results in an increase in the energy barrier to macromolecules viscoelastic relaxation. In addition, erosion resistance was studied during exposure of samples to cavitation tests. According to the obtained results, these materials can be applied in construction and mining industry.

In this work, membranes were synthesized by depositing fluoropolymer coatings onto metal meshes using the hot wire chemical vapor deposition (HW CVD) method. By changing the deposition parameters, membranes with different wetting angles were obtained, with water contact angles for different membranes over a range from 130° ± 5° to 170° ± 2° and a constant oil contact angle of about 80° ± 2°. These membranes were used for the separation of an oil–water emulsion in a simple filtration test. The main parameters affecting the separation efficiency and the optimal separation mode were determined. The results reveal the effectiveness of the use of the membranes for the separation of emulsions of water and commercial crude oil, with separation efficiency values that can reach over 99%. The membranes are most efficient when separating emulsions with a water concentration of less than 5%. The pore size of the membrane significantly affects the rate and efficiency of separation. Pore sizes in the range from 40 to 200 µm are investigated. The smaller the pore size of the membranes, the higher the separation efficiency. The work is of great economic and practical importance for improving the efficiency of the membrane separation of oil–water emulsions. It lays the foundation for future research on the use of hydrophobic membranes for the separation of various emulsions of water and oil products (diesel fuel, gasoline, kerosene, etc.).

“…Two kinds of membranes can realize the oil–water separation, and are suitable for different separation requirements. At present, the preparation methods of superhydrophobic films mainly include dip coating, 10 spray coating, 11 spin coating, 12 sol–gel, 13 layer-by-layer, 14 vapor pressure deficit (VPD), 15 chemical vapor deposition (CVD), 16 electrodeposition, 17 , electrospinning, 18 acid–base treatment, 19 grafting, 20 thermal, 21 plasma, 22 ion beam irradiation, 23 and femtosecond laser. 24 These methods still have the problems of harsh synthesis conditions, cumbersome preparation process, high cost, instability and easy shedding of super-hydrophobic coatings, unrecyclable and continuous use, etc.…”
