Determination of the Glass Transition Temperature of Polymeric Photorefractive Composite from Photo-charge Generation Efficiency Measurements

Conclusions In summary, it has been shown that DSC is not an appropriate technique for determining the T g of polymeric PR composite, since the transitions observed in the DSC curves are weak and relatively broad. Thus, an alternative method has been proposed, consisting on studying the temperature...

Zusammenfassung:Conclusions In summary, it has been shown that DSC is not an appropriate technique for determining the T g of polymeric PR composite, since the transitions observed in the DSC curves are weak and relatively broad. Thus, an alternative method has been proposed, consisting on studying the temperature dependence of photo-charge generation efficiency and identifying T g with the temperature at which tendency of photocharge generation efficiency has reversed.
