Rheological testing with photocrosslinking: (a) variation of storage modulus under irradiation after 60 s stabilization for all the five photoinitiator formulation, (b) variation of storage modulus with 1800 s static pre-incubation with and without replenishment of SPS (1 mM/10 mM Ru/SPS), (c) compare variation of storage modulus between the condition of 1800 s shearing and 1800 s static pre-incubation (red dash line represents the time to turn of the light for static samples and red solid line represents time to turn of the light for shearing samples), (d) variation of storage modulus for LAP under irradiation at different time points and effect of pre-incubation and replenishment of the photoinitiator and (e) variation of storage modulus for Ig2959 under irradiation at different time points and effect of pre-incubation and replenishment of the photoinitiator. Note the 1800 s static pre-incubation was performed in the microtube before applied to the rheometer.
