| 英文摘要 | In this paper, the composite latex particles with a polyacrylate (pa) core and a polydimethylsiloxane ( pdms) shell via 3-(methacryloxypropyl)trimethoxy silane ( mps) as the medium to link the core and shell were prepared by semicontinuous seeded emulsion polymerization and were characterized by transmission electron microscopy (tem), ft-ir, particle size analyzer and x-ray photoelectron spectroscopy (xps). the tem images indicated that the particles containing organic siloxane (d-40) displayed an evident core/shell structure. additionally, the study by ft-ir and xps also revealed that d-4 could be grafted onto the surface of polyacrylate core because there appeared the characteristic peaks of si-o-si group and si 2s and si 2p in the spectra of ft-ir and xps respectively. besides, the atomic ratio of c/si on the surface of the core/shell particles (d-40) was close to the ratio of c/si in the latex of pure pdms that could prove the pa particles were fully covered by pdms and the properties of pdms should be embodied in a maximal level. in order to testify the result, the surface properties of the films produced from the core/shell particles were also investigated by the static contact angle method. compared with the copolymer of pa, the core/shell particles were more effective to create hydrophobic surface, so, the introduction of d4 was capable of obvious increase in water repellency. |
