Photographs of PY-PSBTh physical blend: (a) soon after the PDMS/PS toluene solutions are mixed (notice the solvent phase separated from the organogels); (b) homogeneous and viscous organogel after annealing at 80 °C for 1 h; and (c) final PDMS/PS blend after solvent evaporation, PY-PSBTh; (d) Strain sweep (100 rad/s at 25 °C) of PY-PSBTh dry gel.
