Synthesis of non-migrating of photoinitiators by their immobilization at surfaces, mainly of inorganic (nano)particles.
-
Coupling of moieties generating nitrenes and carbenes under UV illumination to nanoparticles using organosilane linkers (academic secondment).
-
Characterization of the efficiency of the photoinitiators compared to free (i.e., non-coupled) initiators.
-
Tuning of mechanical properties of photocured composites by separating the UV wavelengths which are required to cure the matrix resin and to trigger the photoreaction at the surface.
-
Obtaining of at least one photoinitiator that is less hazardous than the selected benchmark and has comparable performances.
Protocols for the synthesis of photoinitiators with increased skin- and biocompatibility bearing coupling units and their precise characterization.
-
Optimisation of the efficiency of particle-bound initiators for radical and cationic biobased monomers.
-
Modulation of mechanical properties on command for photocured composites formulations. Setting of an appropriate sustainability/safety metrics for photoinitiators, and safety assessment of the newly synthesised photoinitiators.
-
Trained researcher with skills on the synthesis and characterisation of photoinitiators and their surface immobilisation, acquired also during secondments.
