Drying of SnO2 hydrogels: effect of the electrolyte
The effect of the electrolyte (NH+ 4, Cl-) on the drying of SnO2 hydrogels was investigated by linear shrinkage, mass loss, gravimetric thermal analysis and infrared spectroscopy. Results show that the drying mechanism for ...
Gel Type Electrolytes for Dye Sensitized Solar Cells
Effect of electrolyte on the gelation and aggregation of SnO2 colloidal suspensions
Electrolytes may modify the physical-chemical characteristics of colloidal particle interfaces in suspension, which can favour gel or aggregate formation. The influence of NH4Cl loading on the aggregation and gelation of ...
NMR and conductivity study of gelatin-based polymer electrolytes
(TAYLOR & FRANCIS LTD, 2008)
Nuclear Magnetic Resonance spectroscopy (NMR) and complex impedance spectroscopy have been used to study gelatin-based polymer electrolytes plasticized with glycerol and containing lithium perchlorate. The studied samples ...
Plasticized pectin-based gel electrolytes
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Pectin is a natural polymer present in plants and, as all natural polymers has biodegradation properties. Chemically, pectin is a polysaccharide composed of a linear chain of 1 -> 4 linked galacturonic acids, which is ...
Agar-Based Gel Electrolyte for Electrochromic Device Application
(TAYLOR & FRANCIS LTDABINGDON, 2012)
Gel Polymer Electrolytes (GPE) based on agar and containing LiClO4 have been prepared, characterized and applied to electrochromic devices. The ionic conductivity revealed the best result of 6.5 x 10(-5) S/cm for the sample ...
