“…Impact strength is important in most applications because the ability of structures to withstand repeated impacts is critical to the design's robustness, particularly in the transportation and consumer goods industries. As a result, the ability of structures, especially in the transportation and consumer goods industries, to withstand repeated impacts is critical to the robustness of the construction, according to numerous studies of polymer blend effect on impact tolerance [30][31][32] The behaviour of advanced materials suitable for impact resistance was developed and studied by material researchers and designers, therefore, eco-friendly and biodegradability are the most favoured requirements of making green composites, however natural bers, biopolymers and bio-llers could be utilised as sustainable additives for manufacturing biodegradable products [33,34] From numerous bioresources, a number of epoxy thermosets have been synthesized and the challenges and opportunities in developing sustainable epoxy thermosets and materials from bio-based monomeric phenols are presented in various results of mechanical properties such as impact resistance and ame-retarding ability [34,35] Therefore, in the impact resistance of bio-phenolic/epoxy polymer blends were shown in Fig. 7 has resulted the impact resistance was gradually increased as bio-phenolic loading increase from 5 wt% to 20 wt%.…”

Nowadays, researchers continue studies for alternative materials to replace the redundant petroleumbased products. The combination of various polymer mixture process mainly from bio-polymer material as a matrix property could reduce the dependence over petroleum-based polymer, thus the dangerous residue waste from the synthetic polymer in the fabrication process could be eliminated and produce better composite material with lower cost and high performance of composite material in numerous applications. In this study, the effect of bio-phenolic loading and curing temperature on the mechanical properties of bio-phenolic/epoxy polymer blends was investigated. Bio-phenolic/epoxy polymer blends were fabricated with different loading of bio-phenolic resin (5(P-5), 10(P-10), 15(P-15), 20(P-20) and 25(P-25) wt%) and different curing temperature was used which is 100 ℃, 130 ℃ and 150 ℃. The overall mechanical properties of bio-phenolic/epoxy polymer blends were improved as bio-phenolic loading increase and curing temperature increase. Based on the analysis, bio-phenolic/epoxy polymer blends with 20 wt% bio-phenolic showed the best overall mechanical properties. Besides that, 150 ℃ curing temperature was the most suitable curing temperature for bio-phenolic/epoxy polymer blends based on the overall mechanical properties.

“…The above cited family of compounds is becoming more attractive as a substitute for petroleum-derived monomers. A huge amount of work has already been done to exploit their use in several different application fields, ranging from linear polymers, such as polyester, polyurethane and polycarbonates, to crosslinked resins, such as vinyl ester, epoxy and acrylate resins [ 12 , 13 , 14 , 15 , 16 , 17 ].…”

Bio-based monomers represent the future market for polymer chemistry, since the political economics of different states promote green ventures toward more sustainable materials and processes. Industrial pulp and paper processing represent a large market that could advance the use of by-products to avoid waste production and reduce pollution. Lignin represents the most available side product that can be used to produce a bio-based monomer. This review is concentrated on the possibility of using bio-based monomer derivates from pulp and the paper industry for UV-curing processing. UV-curing represents the new frontier for thermoset production, allowing a fast reaction cure, less energy demand, and the elimination of solvent. The growing demand for new monomers increases research in the environmental field to substitute for petroleum-based products. This review provides an overview of the main monomers and relative families of compounds derived from industrial processes that are suitable for UV-curing. Particular focus is given to the developments reached in the last few years concerning lignin, rosin and terpenes and the related possible applications of these in UV-curing chemistry.

“…Conventional thermosetting resins play an important role in, and have changed many aspects of, modern life. [1][2][3][4] However, the constantly increased production and exceedingly poor degradability of synthetic petroleum-based thermosetting resins has limited environmental and economic development. [5][6][7][8][9][10] Additionally, the cross-linking networks of conventional thermosetting resins are highly stable; as such, these resins can not be reshaped or reprocessed by heat or with solvent.…”

The sustainable production of adaptive, recyclable and iminebased dynamic covalent thermosetting resins (DCTRs) presents an opportunity for polymer scientists to address the prevalent environmental and energy concerns associated with current petroleum-based plastics. However, the imine-based DCTRs easily decompose in the presence of water, which can weaken the mechanical properties in imine-based polymers. In this study, we designed oxime-imine DCTRs that are stable in the presence of water and exhibit good mechanical properties. In the presence of one kind of amino group catalyst, the oximeimine DCTRs could be completely recycled. Additionally, these well-designed oxime-imine DCTRs have good mechanical properties, high glass transition temperatures (166°C), and good thermal stabilities. Taken together, this work offers a sustainable solution for the design and manufacture of highvalue degradable materials intended for applications in which recyclability and reusability are indispensable.
