摘要

Abstract

Utilizing the hydrolysis and condensation of the methoxysilyl moieties

organic-inorganic hybrid poly(

-isopropylacrylamide-

-acrylamide-

-3-(trimethoxysilyl)propylmethacrylate) P(NIPAM-

-AM-

-TMSPMA) microgels were prepared

via

two different methods. The first method was that the microgels were post-fabricated from the cross-linkable linear P(NIPAM-

-AM-

-TMSPMA) terpolymer aqueous solutions above the lower critical solution temperature (LCST) of the terpolymer. For the second method

the microgels were directly synthesized by conventional surfactant free emulsion copolymerization of NIPAM

and TMSPMA. The hydrodynamic diameter and stability of the resultant P(NIPAM-

-AM-

-TMSPMA) microgels strongly depend on the pH and temperature of the microgel aqueous solution. The hydrodynamic diameters of the microgels decreased with increasing the measuring temperature. The phase transition temperature of the microgels was found to be around 34℃

which was independent of the initial terpolymer concentration and shifted to lower temperature with increasing the preparation temperature. Increasing the initial amount of AM will enhance the instability of the microgels at high pH values. Moreover

the P(NIPAM-

-AM-

-TMSPMA) microgels obtained from the linear terpolymer had more homogeneous microstructures as compared with the corresponding NIPAM/AM/TMSPMA microgels prepared by one step emulsion copolymerization as revealed by light scattering measurements.
