| Summary: | 碩士 === 國立中興大學 === 化學工程學系所 === 107 === Because there are pests in Taiwan all of the four seasons, the only effective method to prevent those situations is cut off the route of disease transmission. Thus, in the critical situation, the most effective manner of killing pests is using the insecticides. The main components in traditional insecticides are Pyrethrins and Pyrethroids. The vapor of the toxic compound in insecticides would let the human’s health and the environment be injured. Hence, the demands on detecting the harms provoked by toxic compounds become more and more so that the objects including environmental monitoring and health risk assessment, etc. could be facilitated.
The macroporous polymer films with three-dimensional hexagonal closest packing which consists of the ethoxylated trimethylol-propane triacrylate (ETPTA) with uniform pore size where the 2-hydroxyethyl methacrylate (HEMA) were coated on are continuously prepared by a simple, roll-to-roll compatible doctor blade coating technology and utilized as the detectors of the vapor of insecticides.
According to the results, it is observed that the diffracted wavelength by this composite film would change with the insecticide pressure in a short time. Besides, the offsets of the diffracted wavelength could also be adjusted by the pore size of the macroporous films. Based on the apparent changes in color, the content of insecticides around surroundings could be quickly identified by the human’s eye. As reported by the advantageous like the lower energy consumption, lower cost and more environmentally friendly, it is proved that this film could satisfy the demands of human society.
