Dataset description

This study investigated the dissolution of silk multifilament fibres in the ionic liquid 1-ethyl-3-methylimidazolium acetate. The dissolution process was found to create a silk composite fibre, comprising undissolved silk multi-filaments surrounded by a coagulated silk matrix. The dissolution procedure was carried out for a range of temperatures and times. The resulting composite fibres were studied using a combination of optical microscopy, wide angle X-ray diffraction (XRD) and tensile testing. An azimuthal (alpha) XRD scan enabled the orientation of the composite silk filaments to be quantified through a 2nd Legendre Polynomial function (P2). The P2 results could be shifted to construct a single master curve using time-temperature superposition (TTS). The shifting factors were found to have an Arrhenius behaviour with an activation energy of 138 ± 13 kJ/mol. Using a simple rule of mixtures the P2 measurements were used to calculate the dissolved silk matrix volume fraction (Vm), which also displayed TTS forming a single master curve with an activation energy 139 ± 15 kJ/ mol. The tensile Young’s Modulus of each silk composite filament was measured and these results similarly formed a master curve with an activation energy of 116 ± 12 kJ/mol.
