dc.description.abstractThe synthesis of conductive and eco-friendly new chitosan composite biopolymer with a novel aldehyde functionalized ionic liquids (AFILs) was investigated in this work. The AFILs, 1,1 '-(pentane-1,5-diyl) bis(4-formylpyridin-1-ium) dibromide (C5PyBr), 1,1 '-(octane-1,8-diyl) bis(4-formylpyridin-1-ium) dibromide (C8PyBr) and 1,1 '-(decane-1,10-diyl) bis(4-formylpyridin-1-ium) dibromide (C10PyBr) have been synthesized and they were characterized by FT-IR, UV-vis and H-1-NMR and (13) C-NMR, TG, and DSC analyses. The synthesized AFILs, C5PyBr C8PyBr and C10PyBr were used as cross-linker for chitosan biopolymers and the cross-linked chitosan composites, chitosan/1,1 '-(pentane-1,5-diyl)bis(4-formylpyridin-1-ium)dibromide (Ch/C5PyBr), chitosan/1,1 '-(octane-1,8-diyl)bis(4-formylpyridin-1-ium)dibromide (Ch/C8PyBr) and chitosan/1,1 '-(decane-1,10-diyl)bis(4-formylpyridin-1-ium)dibromide (Ch/C10PyBr) were prepared. Herein, the synthesized AFILs have not only cross-linked chitosan, but also provide them the desired novel, functional groups. The prepared chitosan composites were characterized by FT-IR for the analysis of structural, TG and DSC for the thermal behavior, and an electrometer for the electrical conductivity. The electrical conductivity of the prepared Ch/C5PyBr composite was measured as 1.69 x 10(-5) +/- 2.37 x 10(-5) S cm(-1) by the four-point probe at room temperature and this value is higher about 4500-fold than the electrical conductivity of the chitosan.
