Extended model of the photoinitiation mechanisms in photopolymer materials

Liu, Shui ; Gleeson, M. R. ; Sabol, Dušan ; Sheridan, John T. (American Institute of Physics, 2009-11)

In order to further improve photopolymer materials for applications such as data storage, a deeper understanding of the photochemical mechanisms which are present during the formation of holographic gratings has become ...
Holographic grating evolution in photopolymer materials

Gleeson, M. R. ; Kelly, John V. ; Close, Ciara E. ; Sabol, Dušan ; Sheridan, John T. (Optical Society of America, 2007-05-20)

A generalized non-local polymerization driven diffusion (NPDD) model is presented, including the effects of absorption and inhibition. Experimentally obtained growth curves are fit using a four-harmonic numerical fitting ...
Improvement of the spatial frequency response of photopolymer materials by modifying polymer chain length

Gleeson, M. R. ; Sabol, Dušan ; Liu, Shui ; Close, Ciara E. ; Kelly, John V. ; Sheridan, John T. (Optical Society of America, 2008-03-01)

One of the key predictions of the nonlocal photopolymerization driven diffusion (NPDD) model is that a reduction in the extent of the nonlocal effects within a material will improve the high spatial frequency response. The ...
Modeling the photochemical effects present during holographic grating formation in photopolymer materials

Gleeson, M. R. ; Kelly, John V. ; Sabol, Dušan ; Close, Ciara E. ; Liu, Shui ; Sheridan, John T. (American Institute of Physics, 2007-07-26)

The development of a theoretical model of the processes present during the formation of a holographic grating in photopolymer materials is crucial in enabling further development of holographic applications. To achieve ...
Photoinitiation study of Irgacure 784 in an epoxy resin photopolymer

Sabol, Dušan ; Gleeson, M. R. ; Liu, Shui ; Sheridan, John T. (American Institute of Physics (AIP), 2010-03-10)

A deeper understanding of the processes, which occur during free radical photopolymerization, is necessary in order to develop a fully comprehensive model, which represents their behavior during exposure. One of these ...
