File Name : supplementaryfigures2_sbrreconstructionfigac160.pdf Caption : fig. s2 frequency dependent behavior of the sbr (ac160tsa). storage moduli (e'), loss moduli (e''), and loss tangents (tanδ) over a range of frequencies are shown in (a), (b), and (c), respectively. mean am-fm afm reconstructions are compared to control macroscale dynamic mechanical analysis (mdma, squares) and nanoscale dma (ndma, lines) measurements. all data besides the reconstructions have been published previously ¹⁴, and are used here with permission. am-fm afm reconstructions from each of the 13 individual am-fm afm images are also shown in gray. red arrows indicate regions where the reconstruction deviates from the controls by failing to account for all arms in the gmm. e' and e'' for ndma were calculated using the hertz contact model. am-fm afm and ndma were performed using an ac160tsa cantilever. error bars and shading represent the standard deviation.
