(a) Pt-catalyzed crosslinking and (b) light-initiated thiol-ene crosslinking. (c) Rheological characterization of the photocrosslinking of base agent (V-PDMS, 80 wt%) and thiolated crosslinker (S-PDMS, 20 wt%) with DMPA (0.5 wt%) under UV exposure (365 nm, 15 mW/cm2). (d) Compressive moduli of photocrosslinked V-PDMS and S-PDMS with varied concentrations of S-PDMS after UV exposure (365 nm, 15 mW/cm2) for 2 min. The mixing ratios between V-PDMS and S-PDMS were 90:10, 80:20 and 70:30 by weight. (n = 3. Data presented as mean ± s.d.).
