碩士 === 國立臺灣科技大學 === 化學工程系 === 97 === The objective of this work was to prepare and characterize transparent
nanosized silica hydrosols using sodium silicate solution as the monomer,
ultrapure water as the solvent, and acid cation exchange resin ( IR120 ) to
produce activated silicate acid. We studied the influence of initiator, pH,
inhibitor, and the process of concentration on the particle size and
colloidal stability of the silica hydrosols. We discussed nucleation and growth of silica hydrosols by altering the reaction conditions, and collecting samples during different growth times. As a result of this study, we presented the optimum reaction conditions and conversion rate to produce stabilized transparent nanosized silica hydrosols.
