(a) Scheme of the experimental setup for synthesizing cylindrical gels with ordered structures. (b) Proposed microstructure of hierarchically oriented PBDT in the cross-sectional and axial planes of the polymeric gel. (c) Birefringence change of the swollen cylindrical gel and disc gel of QP-2.5-1 under compression in the radial direction. The right columns show observations with the insertion of a 530 nm sensitive tint plate. The strain (ɛ) is noted in each panel. Adapted from Ref. 74 (© 2009 ACS).
