Table 1.
Formulations of spray solutions with monomers and their quantities and the chosen solvent. The amount of the solvent is the same (10 g) in all samples, the amount of photoinitiator in all spray solutions is 1 wt% ratio to combined monomers. Equal stoichiometry (1:1 ratio) of functional groups (−SH for thiol and −C=C for double bonds) was considered in each spray solution.
