| 1 | Vapor and Pressure Sensors Based on Cellulose Nanofibers and Carbon Nanotubes Aerogel with Thermoelectric Properties显示文摘In this work,thermally insulating and electrically conductive aerogels were prepared from cellulose nanofibers(CNF)and carbon nanotubes(CNTs)by environmentally friendly freeze-drying process.The thermal conductivity of neat CNF aerogel is 24 mW/(m・K)with a density of 0.025 g/cm3.With the addition of CNTs into CNF aerogel,the electrical conductivity was significantly increased while the thermal conductivity was increased to 38 mW/(m・K).Due to these interesting properties,the Seebeck coefficient and the figure of merit(ZT)of the CNF/CNTs aerogels were measured and showed that CNF/CNTs aerogel thermoelectric properties can be improved.The compressibility and electrical resistance of the CNF/CNTs aerogel highlighted its pressure-responsive property.A set of volatile organic compounds(VOCs)were exposed to aerogels to monitor the resistance change.The CNF/CNTs aerogel showed high sensitivity and good response to both nonpolar and polar vapors due to the absorption by both CNF and CNTs networks.The prepared CNF/CNTs aerogel is therefore a good candidate for thermal insulation,thermoelectric material,VOCs sensing,and pressure-sensing applications. | Rajendran Muthuraj Abhishek Sachan Mickael Castro Jean-Francois Feller Bastien Seantier Yves Grohens | 2018 | Journal of Renewable Materials2018，6，3： | 2 |

| 3 | Structure-Thermal Conductivity Tentative Correlation for Hybrid Aerogels Based on Nanofibrillated Cellulose-Mesoporous Silica Nanocomposite显示文摘Hybrid aerogels have been prepared by freeze-drying technique after mixing water dispersions of cellulose microfibers or cellulose nanofibers and silica(SiO2)of type SBA-15(2D-hexagonal).The prepared composites were characterized by different analysis techniques such as SEM,hot-filament,DMA,etc.These composites are compared to those previously prepared using nanozeolites(NZs)as mineral charge.The morphology studied by SEM indicated that both systems have different structures,i.e.,individual fibers for cellulose microfibers WP-based aerogels and films for nanofibrillated cellulose NFC-based ones....These differences seem to be driven by the charge of the particles,their aspect ratio and concentrations.These hybrid materials exhibit tunable thermal conductivity and mechanical properties.The thermal conductivity values range between^18 to 28 mW.m^-1.K^-1 and confirm the superinsulation ability of these fibrous aerogels.Synergism on the thermal insulation properties and mechanical properties was shown by adjunction of mineral particles to both cellulose-based aerogels by reaching pore size lower than 100 nm.It significantly reduces the thermal conductivity of the hybrid aerogels as predicted by Knudsen et al.Furthermore,the addition of mineral fillers to aerogels based on cellulose microfibers induced a significant increase in stiffness. | Dounia Bendahou Abdelkader Bendahou Bastien Seantier Benedicte Lebeau Yves Grohens Hamid Kaddami | 2018 | Journal of Renewable Materials2018，6，3： | 1 |
