a Conceptual illustration of the thiol–ene reaction under an alternating electric field. b Piezo-polarization state of ZnO nanoparticles under electric field and plausible mechanism for the E-thiol–ene reaction. c Evolution of Mn over increasing monomer conversion of polymer via E-thiol–ene polymerization. d GPC trace depicting the evolution of polymer molecular weight over time. The polymerization mixture contained 3.00 mmol of TEGDE, 3.00 mmol of EDT, 0.15 mmol Et4NBF4 in 1.50 mL DMF and 210 mg ZnO nanoparticles. The mixture was treated under 8 Vrms and 500 Hz using the AC power supply at varied durations, denoted by the different line colors defined in the legend. Aliquots from the reaction were analyzed by 1H-NMR and by GPC with polystyrene standards.
