Triazatruxene based photosensitizers for efficient visible-light and sunlight-induced cationic polymerization of epoxy resins

Key Points

• Cationic polymerization of epoxy resins shows improved efficiency under visible light and sunlight.
• The incorporation of triazatruxene as a photosensitizer enhances polymerization rates substantially.
• Experimental methods utilized for exposing epoxy resins to different light sources include both visible light and natural sunlight.
• This study highlights the potential for more sustainable polymerization processes using sunlight for activation.
