The source of conductivity and proton dynamics study in TEMPO-oxidized cellulose doped with various heterocyclic molecules

摘要: Our manuscript focuses on the study of proton conductivity phenomena caused by a high degree mobility and dynamic movement protons that occur in some hybrid composites obtained from TEMPO oxidized cellulose doped with three heterocyclic compounds. The first stage consists preparation organic matrix, reaction conditions being chosen so as to allow incorporation many carboxyl groups possible. numerous COOH groups, introduced after oxidation backbone, successful attachment N-base molecules, such as: 1-hydroxybenzotriazole (HBT), imidazole (IM), 7-azaindole (AI). prepared cellulose-based powder (OxC-HBT, OxC-IM, OxC-AI) were firstly analyzed using extensive FTIR study. Different explanations regarding nature source proposed based experiments. A good thermal stability samples has been revealed analyses. Moreover, showed values both at lower higher temperatures, for example, under anhydrous conditions, found equal 1.2 × 10−1 S/m composite containing IM 2.3 × 10−2 material HBT. activation energies also calculated discussed each dopant. use derivatives natural polymers, i.e. cellulose, create prerequisite cheap, non-hazardous environmentally safety approaches find new biopolymer materials conductive properties potential application fuel cell technology.
