Facile Approach for the Synthesis of Performance-Advantaged Degradable Bio-Based Thermoset via Ring-Opening Metathesis Polymerization from Epoxidized Soybean Oil

Abstract

Design and synthesis of polymeric materials from sustainable feedstocks can partly mitigate environmental polymer pollution, and hence, it has received constant attention. This work aims to synthesize a degradable bio-based thermoset via ring-opening metathesis polymerization (ROMP) from epoxidized soybean oil (ESO). ESO was converted to norbornene-functionalized ESO first, and then, this functionalized ESO was rapidly generated to a thermoset via ROMP. The ESO-based thermoset exhibits promising thermal properties and mechanical performance, is available for fabrication of composites, and can be fully degraded into small molecules and oligomeric species under aqueous NaOH or KOH. Moreover, the functionalized ESO can copolymerize with norbornene to form partially degradable copolymers. This approach can be used to synthesize degradable vegetable oil-based thermosets for various applications and for environmental sustainability.

Waterborne Lignin-Based Epoxy Resin: A Green and Effective Chemical Cross-Linker to Form Soy Protein-Based Wood Adhesive with High Performance

“…It should be noted that about 90% of the commercial epoxy resins were prepared from nonrenewable petroleum-based raw materials, which did not follow the sustainable development and circular economy concept. Consequently, the design of ecofriendly, high-performance epoxy resin from renewable and nontoxic resources has attracted tremendous attention. − …”

Planting Multiwalled Carbon Nanotubes onto Epoxidized Soybean Oil-Based Vitrimer to Construct a Biobased Photothermal Superhydrophobic Coating with Self-Healing and Closed-Loop Recyclability for Anti/Deicing

“…Vegetable oil has recently been used by numerous researchers to create a variety of plant oil-based polymers because of its advantages in terms of low cost, easy availability, and wide availability. , Among them, epoxy soybean oil (ESO) is considered to be the most promising alternative to petroleum-based resources due to its advantages of large-scale production, functional tunability, and degradability. − By using different types of curing agents and ESO curing, biobased epoxy resins can be endowed with different functions, such as antibacterial, superhydrophobic, and UV shielding. − However, the curing agents used in current ESO-based superhydrophobic coatings mostly come from petroleum-based resources, which greatly reduce the biobased content of the materials. It is necessary to develop a fully biobased epoxy resin for the sustainable development of superhydrophobic coatings. , …”

Achieving performance‐advantaged polydicyclopentadiene via sequential ring‐opening metathesis polymerization and radical reaction

“…[3][4][5][6][7] PDCPD also gives us constant surprise: the polymerization features make it available for instance in rapid energy-efficient manufacturing and 3D printing, [8][9][10][11][12] fabricating autonomic healing materials, foams and patterns [13][14][15][16][17][18][19][20][21] and designing degradable thermosets. [22][23][24][25][26] A large number of investigations on PDCPD have been performed; nonetheless, lots of work still needs to be done. For example, the application of polymers in some areas like microelectronics, automotive components and medical devices requires a performance above 177 °C.…”
