| Abstract: | Polyurea microcapsules were prepared by the method of interfacial polymerization with triethylene tetraamine modified by glutaraldehyde as water-facial monomer and tolylene-2, 4- diisocyanate as oil-facial monomer. When the stirring rate was 800 - 1 000 r/min and the concentration of emulsifier OP - 10 was 0.05 -0. 12 mol/L, microcapsules with certain mechanical strength and tenacity were obtained and did not crack when dried. They were water-proof arid heat-proof and the wall thickness was about 2 I~m. Electrophoresis was observed under DC electric field. The response time was 0.2 s. |
