Epoxy‐based thermosets are one of the most popular matrix materials in many industries, and significant environmental benefits can be obtained by developing a recyclable variant of this widely utilized material. Incorporation of a bio‐based disulfide additive within a commercial epoxy system leads to a cross‐linked material that can be fractionated under mild and environmentally benign conditions. The material has been analyzed by FTIR and solid‐state NMR. Furthermore, modified epoxy matrices with low additive concentrations are demonstrated to have similar mechanical and thermal properties compared to commercially available benchmarks. Thus, additive formulation and fractionation based on green chemistry principles have been demonstrated, and a recyclable epoxy matrix has been developed.
