Crystallization is widely used in various industries. Polyphenols like caffeic acid have high antioxidant and adhesive properties, which can make polyphenols attached to the surfaces of polymer particles. This interaction might lead to nucleation in crystallization. The polyphenol crystals are expected to form polymer-polyphenol composites which can be used as new medical material. In the crystallization with a foreign body, heterogeneous nucleation is known to be preferable. Crystallization behavior changes can lead to change of crystal morphology and nucleation time. In this study, crystallization of polyphenol occurs in presence of poly-caprolactone (PCL) microparticles. The effects of particles in crystallization varies by particle size and concentration, material concentration, method of crystallization like cooling or drowning out. Polyphenol crystallization with microparticle would be a way to make another type of composite material and functional crystals. |
