Abstract:
PMMA microspheres were synthesized in distilled water by ultrasonic-assisted emulsion polymerization. The average particle size of PMMA microspheres was dependent marktedly on the kind of surfactant used. Porous (pr-) In 2 O 3 powders were prepared by ultrasonic-spray pyrolysis of In(NO 3 ) 3 aqueous solution containing the PMMA microspheres synthesized. The NO 2 response of pr-In 2 O 3 was much larger than that of conventional In 2 O 3 powder prepared by the similar technique employing PMMA-free In(NO 3 ) 3 aqueous solution. The introduction of controlled macroporous structure into the powder of the sensor material was found to be effective for improving NO 2 response properties.
