Bulk characterisation of PDMS by (a) Oscillatory rheology showing the frequency sweeps with frequencies from 0.1–100 Hz at an oscillating displacement of 10−4 rad for PDMS samples with % Crosslinker ranging from 1–10% a minimum of three repeats were conducted on each sample and (b) microindentation showing representative stress relaxation curves, of samples strained to 10% strain at a rate of 1%/s and a hold time of 5 min, each test was repeated three times. Error bars showing the standard deviation.
