Thermal Degradation of Hybridize Doped Poly(Dioctylfluorene) Film with Polydimethylsiloxane

The purpose of this study is to evaluate the thermal degradation of hybridize doped poly(dioctylfluorene) (PF8) film with polydimethylsiloxane (PDMS). The hybridized PF8/PDMS films were produced using solvent casting technique. The poly(dioctylfluorene) was dissolved using chloroform and subsequently polydimethylsiloxane was added prior mixing. Three different concentrations of PF8 were used to prepare the doped film. After casting, the samples were put in an oven at 100°C for 5 minutes for curing process. Later the thermal degradation test was conducted on the prepared sample for the duration of 1 hour, 2 hours, 3 hours and 24 hours to observe the effect of temperature on the photoluminescence properties of PF8. UV-visible spectroscopy was mainly used to measure the absorption intensity of the hybridized materials. It was configured that the optimum doped concentration for PF8 with PDMS is by using 5.0×10-3 mol of PF8. This is due to a good solubility of PF8 and easy to be casted.
