Figure 5.
(a) Bulk mechanical characterisation of PAAm by oscillatory rheometry (frequency Sweeps) across a range of AAm and crosslinker concentrations (see Table 1 for details of compositions of PAAm1-4, as indicated in the legend), frequencies tested were from 0.1–100 Hz at an oscillating displacement of 10−4 rad on a minimum of three repeats and (b) comparison of the modulus of the softest PAAm sample measured moduli with and without functionalised geometry and between bulk (rheology and micro indentation) and local (nanoindentation by AFM) testing methods. Error bars showing the standard deviation.
