Abstract:

A eugenol-based carboxylate surfactant (Eu-10) was successfully synthesized from eugenol by methyl esterification, etherification and saponification. The surface activity was investigated by surface tension method and fluorescent probe method. The critical micelle concentration (cmc) of Eu-10 was 3.98 mmol/L at room temperature. Eu-10 contains an unsaturated double bond. Nanospheres copolymerized by styrene and Eu-10 were successfully prepared through emulsion polymerization using Eu-10 as emulsifier and monomer. The structure and morphology of the samples were observed by scanning electron microscope and transmission electron microscope. The results showed that due to the amphiphilicity of Eu-10, the nanospheres thus obtained had a core-shell structure. The effects of surfactant concentration, initiator concentration and polymerization temperature on the particle size of nanospheres were investigated. The particle size of the nanospheres could be effectively adjusted. This surfactant derives from the natural product eugenol and expands the application of natural products in the preparation of new materials.

Key words: eugenol, surface activity, emulsion polymerization, core-shell structure, nanosphere
