  In this research, the composite nanofibers of polyvinylidene fluoride/polydistylene/graphene oxide (PVDF/PDA/GO) have been produced and their thermal and choromic properties have been investigated.For this purpose, samples of PVDF/PDA/GO were produced. The results of examining the morphology of the produced nanofibers shows that the diameter of nanofibers is significantly decreased and the uniformity of the nanofibers increased by adding GO to the nanofibers. The decrease in nanofiber diameter causes increase in specific surface area of them. The increase of nanofibers specific surface area helps to improve the sensitivity of them. This was confirmed by reflective spectrophotometric test and their high color response to methanol solvent. Also, by heating the sample, it was observed that the produced samples are sensitive to 60 ° C and therefore, they are thermochromic. Because of choromic-thermal properties of PVDF/PDA/GO composite nanofibers, they can be used as a type of chromic sensors and/or thermal sensors. In PVDF/PDA/GO composite nanofibers, graphene oxide enhances the chromic sensitivity responses of polyvinylidene fluoride/polydiacetylene nanofibers. تفاصيل المقالة
