a Swelling ratio (red columns) and polymer–solvent interaction affinity of various hydrocarbon (HC) solvents with polystyrene (blue columns), and their static dielectric constant at 10 kHz (yellow columns). b Photographs of initial polystyrene (PS) and PS organogels fully swollen with various HC solvents. Phenyl octane is chosen as a main solvent component for the AINO, due to its moderate swelling, low dielectric constant, and water solubility. c Elastic modulus and rupture stretch of the AINOs based on phenyl octane as a function of their polymer volume concentration from 1 to 0.153 (pure PS to fully swollen state). d Stress–stretch curves of the AINOs with different phenyl alkanes at polymer volume concentration of 0.65. e Static dielectric constant of the elastomeric AINOs and their constituents (PS and phenyl octane) at 10 kHz. Values in a, c, and e represent the mean and standard deviation (n = 3–5).
