Abstract

Correction for ‘Epoxy resin with exchangeable disulfide crosslinks to obtain reprocessable, repairable and recyclable fiber-reinforced thermoset composites’ by Alaitz Ruiz de Luzuriaga et al., Mater. Horiz., 2016, 3, 241–247, DOI: 10.1039/C6MH00029K.

The authors have detected an error in the calculation of the activation energy and vitrimer temperature. In Fig. 1b, log τ should be plotted on the y axis instead of ln τ. Due to this error, the calculated activation energy is incorrect and the energy should be multiplied by 2.3 (1/log e). The correct activation energy is 126.5 KJ mol⁻¹ and the correct calculated vitrimer temperature is 75 °C. The authors apologise for this error and state that this error does not affect any of the scientific findings and interpretations.

A detailed list of changes is provided as follows:

• The correct version of Fig. 1b is shown below

Fig. 1 (b) Fitting of the relaxation times to the Arrhenius’ equation (R-square = 0.946).

• On page 243, “From this equation, an activation energy (E_a) of 55 kJ mol⁻¹ was calculated for the dynamic epoxy network 5. Such activation energy is lower than other reported systems…” should be changed to “From this equation, an activation energy (E_a) of 126 kJ mol⁻¹ was calculated for the dynamic epoxy network 5. Such activation energy is similar to other reported systems…”

• On page 243, “For our dynamic epoxy system 5, the hypothetical T_v value obtained was −13 °C, which is well below its T_g (127 °C from DSC).” should be changed to “For our dynamic epoxy system 5, the hypothetical T_v value obtained was 75 °C, which is well below its T_g (127 °C from DSC).”

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
