چکیده
|
Licl-doped mesoporous silica mcm-48 with cubic mesostructure, using a different doping concentration of licl, has been prepared. the licl-mcm-48 type materials were characterized employing xrd, ft-ir, sem, and nitrogen adsorptiondesorption isotherm. we had the humidity sensors on a ceramic substrate with two ag-pd interdigital electrodes with five fingers. the sample with 15 wt% licl-doped mcm-48 shows an excellent linearity in the whole humidity range of 11%-97%. it has very good response and recovery time, about 22 and 30 sec, respectively.
