- Abstract
- The object of our research is to observe the expression of 1D lamellar photonic crystal color depending on difference molecular weight of PolyStyrene-Block-2-Vinyl Pyridine(PS-b-P2VP) (52k-57k, 84K-69k, 102k-97k) and different coating solvent (propylene glycol monomethyl ether acetate (PGMEA), tetrahydrofuran (THF)). Color changes of photonic crystal would be reported through a simple method. 1D lamellar photonic crystal was made by the same molecular weight of Poly Styrene-block-Poly-2-Vinyl Pyridine (52K-57K) in different coating solvent tetrahydrofuran (THF) and propylene glycol monomethyl ether acetate (PGMEA). After having done spin coating, we accomplished annealing. Six different results was obtained through experiments. A variety of color expressions was analyzed through UV visible spectrometer.
