Abstract In developing an organic light-emitting diode (OLED) panel for a foldable smartphone (specifically, color filter on encapsulation) aimed at reducing power consumption, the use of new optically clear adhesive (OCA) that blocks UV light was crucial. However, incorporation UV-blocking agent within OCA presented challenge, as it restricted traditional UV-curing methods commonly used in manufacturing process. Although visible-light curing technique producing proposed, its slow speed posed barrier to commercialization. Our study introduces highly efficient photo-initiating system (PIS) rapid production OCAs utilizing visible light. We have carefully selected photocatalyst (PC) minimize electron and energy transfer agents chosen co-initiators allow faster more PC regeneration compared previously established amine-based co-initiators. This advancement enabled tenfold increase OCAs, while maintaining their essential protective, transparent, flexible properties. When applied OLED devices, this demonstrated protection, suggesting potential broader application safeguarding various smart devices.

Abstract Functional inks for light‐based 3D printing are actively being searched able to exploit all the potentialities of additive manufacturing. Herein, a fast visible‐light photopolymerization process is showed conductive PEDOT:PSS hydrogels. For this purpose, new Type II photoinitiator system (PIS) based on riboflavin (Rf), triethanolamine (TEA), and poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) investigated visible light acrylic monomers. has dual role by accelerating photoinitiation providing conductivity obtained Using PIS, full monomer conversion achieved in less than 2 min using light. First, PIS mechanism studied, proposing that electron transfer between triplet excited state dye ( 3 Rf*) amine (TEA) catalyzed PEDOT:PSS. Second, series poly(2‐hydroxyethyl acrylate)/PEDOT:PSS hydrogels with different compositions photopolymerization. The presence negatively influences swelling properties hydrogels, but significantly increases its mechanical modulus electrical properties. also tested commercially available Digital Light Processing (DLP) printer (405 nm wavelength), obtaining high resolution 500 µm hole size scaffolds.
