Fig. 2: Rheological properties of photo-tunable mechanical transformation.
From: Unusual photo-tunable mechanical transformation of azobenzene terminated aliphatic polycarbonate
a and b are the storage modulus (G′) and loss modulus (G″) of trans-rich and cis-rich AZ-APCs vs. frequency at room temperature, respectively. c and d are the stress-strain curves of trans-rich and cis-rich AZ-APCs, respectively. The inset photos show that the strain of cis-rich AZ-APC is smaller than the trans-rich one under the same test conditions (length 12 mm, width 2 mm, thickness 1.5 mm, strain rate 0.33 s−1).
