Sugarcane Bagasse-Derived Activated Carbon- (AC-) Epoxy Vitrimer Biocomposite: Thermomechanical and Self-Healing Performance

Abstract

Vitrimeric materials have emerged as fascinating and sustainable materials owing to their malleability, reprocessability, and recyclability. Sustainable vitrimeric materials can be prepared by reinforcing polymeric matrix with bioderived fillers. In the current work, a sustainable vitrimer is prepared by incorporating biomass-derived activated carbon (AC) filler into the epoxy matrix to achieve enhanced thermal and mechanical properties. Thus, prepared biocomposite vitrimers demonstrate a lower-temperature self-healing (70°C for 5 min) via disulfide exchanges, compared to the pristine epoxy vitrimers (80°C for 5 min). Significantly, the self-healing performances have been studied extensively with the flexural studies; and changes in material healing efficiency have been demonstrated based on the observed changes in modulus.

Sustainable smart anti-corrosion coating materials derived from vegetable oil derivatives: a review

“…Leaving an impression of interest, sustainable polymeric protective coatings have been in prime focus for corrosion inhibition of metallic surfaces and thus explored in this report. 6,42 Along with the inherent properties of vegetable oils, external materials/ groups can be easily coupled due to the presence of different functional moieties in oil, as required for different coating applications. [64][65][66] 2.…”

“…renewable substances like cellulose, starch, sugar, etc. [4][5][6] Vegetable oils are the centre of attention owing to their favourable chemical structure, availability, cost, and unsaturated sites for functional group fabrication, thus advantageous for designing the molecules from scratch. 78 A variety of vegetable oils, e.g.…”

“…For each material, the proper, different combination of treatments should be found and optimised. It can also provide the self-healing properties of the structure [ 27 ]. In some cases, animal sources are efficiently used.…”

Bio-Vitrimers for Sustainable Circular Bio-Economy

“…Rana et al has reported a sustainable vitrimer, prepared by incorporating biomass-derived activated carbon (AC) filler into the epoxy matrix [ 81 ]. The epoxy vitrimer has been prepared in single step reaction with bisphenol A diglycidyl ether (BADGE) and 2- aminophenyl disulfide (2-AFD) at 80 °C for 15 min and then added a different percentage of activated carbon dispersed solution into that.…”
