Research on Preparation and Properties of Coated Polyether Silicone Microencapsulation Based on Polystyrene
Department of Ministry of Science, Ordnance Engineering College, Shijiazhuang, Hebei, China
By the method of interfacial polymerization, the novel microcapsules were prepared with polystyrene as wall material and polyether silicone as core material. In order to demonstrate the morphologies, particle size distribution and properties of microcapsules, scanning electron microscopy (SEM), laser particle size analysis and infrared spectroscopy (FTIR) are also applied in the experiments, and the thermal stability of microcapsules is obtained by thermal gravimetric (TG) and differential scanning calorimetry (DSC). The material ratio (core to wall in weight) of microcapsules and stirring rate ratio are discussed. The results show that under the optimum process conditions of a material ratio (core to wall in weight) which is 4:10 and agitating rate of 500r·min‒1, the synthesized polyether silicone microcapsules have a higher yield and the coating and densification properties; their average size is 210μm, and the thermal stability temperature can reach up to 390°C.
Key words: microcapsules / polyether silicone / polystyrene / interfacial polymerization / thermal stability
