Volatile organic compounds (VOCs) sensors are the imperative technology of modern life for environmental monitoring. There are no ending quests for low cost, robustness, high sensitivity, high reproducibility and high selectivity sensors. The program entitled “The study of surface plasmon coupling enhanced volatile organic compounds sensor and the correlation between microstructure and optical properties” is a two-year program. In the 1st year, we will synthesize Ag nanoparticles and Au nanoparticles, and we will modify their nanoparticle surfaces with conducting ligands. Moreover, we will fabricate VOCs sensing chips by using electrospinning technique. The VOCs sensing chips with high specific surface area will be made of metal nanoparticle/polymer composites, and their characteristics are high absorbance and high sensitivity. In the 2nd year, we will develop a novel VOCs sensors consists of disposable sensing chip and its optical measurement system. The finite-difference time-domain (FDTD) method will be adopted to simulate different metal nanoparticle/polymer nanocomposites, and we expect to find that the size and location of metal nanoparticle on nanocomposites played a vital role in the optical properties. This research program will provide us an opportunity to explore new area of material research for VOCs sensor applications. This two-year program is based on the results of metal nanoparticles/P3HT materials to develop commercial viable VOCs sensor system for the demanding of the world market. During the 2 years, we plan to publish 6 SCI journal articles, 8 conference articles and file 1 patent application.
