The phase separation of APCNs can be investigated by differential scanning calorimetry (DSC) to establish if there are two glass transition temperatures (Tg) that correspond to the individual polymers. While conventional PHEA-l-PDMS APCNs have two glass transition temperatures, at -124 °C and 8 °C corresponding to PDMS and PHEA, respectively, the HCNC-P with different amounts of HCNCs had a single Tg between 32 -35 °C (Figure ). This result is consistent with our previous report, in which dynamic mechanical analysis (DMA) data showed that peptide-
