摘要：
The effect of prepolymer structure on the reflection efficiency and volume shrinkage of holographic gratings based on polymer-dispersed liquid crystals (PDLCs) was studied. It was found that reflection efficiency increased with decreasing molecular weight of the polyurethane (PU) segments bridging the cross-linked acrylate domains and with the decrease of chain rigidity of the hard segment of PU. For this particular matrix system, volume shrinkage increased with increasing chain flexibility and cross-linking density, corresponding to increases in the reflection efficiency. Real time measurement of reflection efficiency during curing showed that high functionality polypropylene glycol (PPG) gave the shortest time to arrive at the saturation value although an optimum PPG functionality exists for the maximum reflection.
