Plastic pollution in the marine environment and oily wastewater generated in industry are now recognized as a real threat, as they adversely affect the environment and cause health issues to living organisms as well. Nevertheless, the current methods for both oil/water separation and plasticizer removal are complex and costly. In this regard, a low-cost and environment-friendly superhydrophobic/superoleophilic material has been developed. Cotton sponge (CS) coated with polybenzoxazine (Pbz) and stearic acidfunctionalized carbon balls (CBS) [i.e., CS-Pbz-CBS] acts as a superhydrophobic/ oleophilic material. By employing surface modification of CS with Pbz-CBS, the hydrophilic CS gets transformed into superhydrophobic CS-Pbz-CBS possessing a water contact angle of 153°. A surface morphological study indicated the selective wettability produced by CS-Pbz-CBS materials as a result of tuning their surface composition and surface roughness as well. In addition to it, the prepared material CS-Pbz-CBS (6%) also possesses excellent mechanical durability, exhibits fast and efficient separation of oil− water mixtures, and can act as an effective material for plasticizer removal. Moreover, the prepared material, CS-Pbz-CBS (6%), has a volumetric absorption capacity, Q w (v/v), of 83.51 for CHCl 3 and provides a 95% separation efficiency for oil/water mixtures. The detailed investigation related to the preparation of these materials and their applicability in oil/water separation and plasticizer removal is analyzed.

“…The results indicate an improvement in the thermal and mechanical properties and corrosion resistance. The study also concluded that this work can be considered an effective way to use waste products and sustainable biomaterials to develop high-performance hybrid composites [5]. The study dealt with the mechanical properties of epoxy composites that were reinforced with two types of natural waste as a micro filler, with different weight ratios and particle size, pollen 50 µm and sea shells 75 µm.…”

Mechanical properties and thermal conductivity of epoxy composites reinforced with recycled clamshell container waste as a micro filler (RCCF) were studied. The studies have been carried out to identify the influence of the two variables, the heating time periods (HT) within the range of 2, 4, 6 min., and wt % within the range of 1 %, 2 %, 4 % of recycled clamshell container waste that has been used as a reinforcing filler of epoxy composites. Recycling polyurethane waste aims to control and maintain a pollution-free environment, which is currently considered a difficult issue in addition to achieving low-cost aspects in preparing the composites. According to the method of no-combustion heating, the clamshell waste was converted from the natural plastic state into solids that were later made into 75 μm micro filler by grinding. Composites were ranked using grey relational analysis (GRA). The effect of each control parameter on response variables was analyzed by the Taguchi method. Using MINITAB 19 software, regression equations were obtained for each variable of mechanical properties and thermal conductivity to predict the properties of epoxy composites. The results of the addition of recycled clamshell container waste to epoxy resin show an improvement in the mechanical properties and thermal conductivity of the composites. The optimal value of the two factors was at HT2wt2, i.e. HT and wt % of 4 min and 2 %, respectively. The optimization values for the bending strength, impact strength, tensile strength, stiffness and thermal conductivity are 68.2 MPa, 10.348 kJ/m2, 21.08 MPa, 80 Shore D and 0.504 W/m·C°, respectively. The proposed Taguchi methodology based on grey relational analysis has been shown to be effective in solving multi-feature decision-making problems.

“…127,128 Besides, it could be doped with fillers to further improve performance. 129 Owing to the limitation of Mannich reaction site in urushiol, one unit phenolic hydroxyl group can be retained, which could promote the ring-opening polymerization of oxazine ring resulting in a lower curing temperature (181 C). In addition, the double bonds in the long chain alkyl group are considered to be simultaneously initiated when the polymerization of oxazine occurs, leading to a resin with excellent toughness and high elongation at break.…”

Due to the rapid depletion of crude oil and serious environmental pollution, the synthesis of polymers from renewable resource is becoming more and more important. Up to now, a great variety of biomass and bio-based platform compounds have been taken to prepare the polymers. However, as two representative thermosetting resins, epoxy and benzoxazine resin derived from renewable feedstocks only obtain limited attention compared with the popular bio-based plastics, including PLA, PBAT and PHBV etc. The reason might be that the properties of previously reported thermosetting resins directly obtained from biomass are usually unsatisfied, and their application fields are limited. In this paper, the latest development on the synthesis of highperformance bio-based epoxy and polybenzoxazine resins are reviewed. In addition, to further broaden their applications, the functionalization strategies are also summarized. The objective of this work is to help us fully aware the present situation of bio-based thermosetting resins and then promote their faster development, especially practical application.
