METAL OXIDE HYDROGELS AND HYDROSOLS, THEIR PREPARATION AND USE
摘要
<p>A process for preparing a hydrosol of one or more metal oxides, e.g. titanium dioxide, comprising preparing a metal alkoxide solution in a water-miscible organic solvent, e.g. an alcohol; providing an aqueous solvent; mixing the metal alkoxide solution with the aqueous solvent in a volume or weight proportion to form a single-phase aqueous sol colloid (hydrosol) of hydrated metal oxide in absence of a non-ionic block polymer surfactant. Also disclosed is a corresponding hydrogel; water- insoluble particles encapsulated in hydrated metal oxide and a process for their encapsulation; uses of the encapsulation products.</p>
