Paper published in SPIE 2020

Congratulations to Abi Collins, Thomas Southern, Morton Lyu and Mike Bennison whose SPIE Proceedings manuscript entitled Photoactive organic-inorganic hybrid polymer waveguides for optical device technologies from the Photosensitive Materials and their Applications Conference has been published.

This work reports on the mechanical and optical properties of low molecular weight ureasils and the relationship between the molecular weight of their precursors and these properties. An array of techniques including steady-state photoluminescence and Fourier-transform infrared spectroscopy, 4-point flexural testing, and uniaxial tensile testing are used.

A relationship was observed between the flexural and elastic moduli of these ureasils and their molecular weight. The presence of unbound urea in samples was related to their water contact angle and stiffness. These relationships can be used to develop waveguide materials with tunable properties.
