In this work we have studied, by light transmission, the effects of either UV or high temperature exposure on the electro-optical properties of cellulose derivatives based PDLC type cells prepared from hydroxypropylcellulose (HPC) and HPC cross-linked with 1,4 - diisocyanatobutane (BDI) (7,0 % w/w). The time evolution of the electro-optical properties of different cells, some under UV exposure, and others under high temperature (65°C), was recorded for times up to 7 days. Two sets of cells were analysed, one with electric field off during exposure, the other with electric field on. The results obtained show that no significant changes of the electro-optical properties of the cells occurred under the studied conditions, meaning that these systems are very stable and so good candidates for industrial applications.
