P5.2 - The Effect on the Gas Selectivity of Gas Sensors by Binder in SWNTs Solution

Seongjeen Kim, Byungmin Gam, Hojung Lee, Jungtak Han & Gungwoon Lee
In this work, we investigated the effect of TEOS and VTMS binders in single walled carbon nanotube(SWNT) solution for imparting selectivity as well as increasing sensitivity to nanotube sensors. Generally binder as organic compound is blended in SWNT solution to adhere to substrate well, and the surface of hydrolyzed binder remain generally functionalized with its own group when it becomes hardened. TEOS and VTMS surrounding SWNTs after hydrolysis remain functionalized to -OH and -CH=CH2 groups,...
