Table 1. Swelling in the thickness of cured PDMS after soaking in 3 different solvents for 2 hours.
Solvent | Ratio of thickness after soak to thickness before soak |
Water (23°C) | 1.00 |
Tert-butyl alcohol (45°C) | 1.05 |
Hexane (23°C) | 1.31 |
Standard deviation divided by mean in all 3 cases was less than 1%.
