Kurzfassung englisch:
The in situ characterization of thermoset formation is challenging, due to crosslinking reactions with subsequent insolubility of the final polymer network. When focusing on light-triggered reactions the experimental set-up becomes even more complex. Photopolymerization has gained increasing efforts for the development of advanced photopolymerizable resin systems (e.g. thiol-ene, epoxy-based, hydrogels) in the fields of coatings, 3D-printing and biomaterials. This has subsequently called for the development of more versatile analytical instruments.
We present a plate-plate rheology set-up with integrated options of real time near- and mid-IR analysis, UV/VIS or LED curing, and additional Peltier heating system. With this unique instrument prototype we are able to evaluate a broad spectrum of photopolymerizable resins with respect to their chemical and mechanical photocuring characteristics.
