The kinetics of thermal processes in imidazole-doped nanocrystalline cellulose solid proton conductor

Effect of imidazole‐doped nanocrystalline cellulose on the characterization of Nafion films of fuel cells

“…Above 450°C, the skeletal structure of cellulose was damaged and formed carbon graphite and levoglucosan products. 3 The degradation process of the CNC/Im sample can be divided into three main stages. The first is the desorption of humidity, which weakened hydrogen interaction with the hydroxyl group.…”

“…The following step was due to the decomposition of functional groups on cellulose molecules. Above 450 °C, the skeletal structure of cellulose was damaged and formed carbon graphite and levoglucosan products 3 . The degradation process of the CNC/Im sample can be divided into three main stages.…”

“…These materials were designed as a new class of proton-conducting solid material in which the conduction pathway includes heterocyclic molecules instead of water molecules. 3 Smolarkiewicz et al 4 used imidazole doped into MCC and obtained membranes with a proton conductivity of approximately 2 × 10 −4 S m -1 under anhydrous conditions at 160°C. The authors also announced the effect of the doped imidazole content on conductivity of the materials.…”

“…Biopolymers such as bacterial cellulose (BC), microcrystalline cellulose (MCC), cellulose nanocrystals (CNC), alginic acids or derivatives of chitosan that have been doped with N ‐heterocyclic molecules such as imidazole, benzimidazole and pyrazole seem to have great potential as materials to fulfill these requirements, and are being extensively studied. These materials were designed as a new class of proton‐conducting solid material in which the conduction pathway includes heterocyclic molecules instead of water molecules 3 . Smolarkiewicz et al 4 .…”

Thermal stability of optical fiber coatings: comparison of experimental thermogravimetric approaches

“…It is also worth noting that, since E α can vary with the degree of conversion, the E α magnitude determined from FWO and KAS methods represents some weighted average over the range 0-α. FWO and KAS approaches are widely used and typically there is a good agreement between E α magnitudes determined via those methods [27][28][29][30][31][32][33][34][35][36][37][38].…”
