Specifically, the shift-factor for estimating the modulus at 250 Hz and 47 °C (to match with AFM data described below) was calculated by extrapolation of existing data using the Williams-Landel-Ferry (WLF) equation. The master curves obtained from DMA are shown in the Supporting Information (Figure ). showing the AFM colloidal probe configuration to measure dynamic mechanical properties across the layered polymer interphase, using a range of probe radii.
