Photo- and thermally active dual-cure precursors development for 3D printable buttle-brush like elastomer. Photocrosslinkable polymeric materials exhibit several limitations in their thermal stability and mechanical properties, limiting their applications toward high-performing usage and deployment in extreme environment. We synthesize dually-active precursors to allow UV printing and formation of semi-interpenetrating network upon thermal curing to create highly stretchable, buttle-brush like elastomers. We investigate the chemistry and architectural role of reactive diluents, their impact in micro-phase separation during UV and thermal processing and their final mechanical properties. This research builds the foundation for modification of polymer precursor backbone suitable for material property tuning, exhibiting compatibility with high-speed AM process such as micro-CLIP printing [8].
