In our studies, different kinds of photosensitive materials for information storage devices have been studied. We synthesized the polymer through the surface relief grating (SRG) fabrication with a diode-pumped solid-state laser (DPSS) of 532 nm. As a result of the measurement of the diffraction efficiency (DE) of the polymer synthesized by using a low power DPSS laser at 633 nm, a low diffraction efficiency was obtained, even after 15 min of exposure. In order to solve this problem and reduce the DE measurements time, we tried to introduce various ionic liquids (ILs) at the polymer. Through various ILs such as imidazolium ILs and ammonium ILs, We have investigated the DE and the measurement time of the polymer with ionic liquids, as a result, it was confirmed that the polymer with ionic liquids showed better results. These studies have not been conducted with azo-polymer and IL mixture in past. Hence, these results seem to be beneficial in the field of polymer chemistry and holographic research.
