Fabrication of Polydiacetylene Fibrous Microcrystals by the Reprecipitation Method

Abstract

Abstract The size and morphology control of polydiacetylene microcrystals has been investigated by changing preparation conditions such as temperature and added surfactant in the reprecipitation method. As a result, fibrous microcrystals (diameter: 50 nm, length: 5–10 μ) of conjugated polymers were interestingly fabricated under an optimum condition. The formation mechanism of polydiacetylene fibrous microcrystals and their optical properties were also investigated.
