Recently, the preparation of the compound and complex colloid that the researcher of physics of high polymer of place of chemistry of Chinese Academy of Sciences and chemical state key laboratory devotes oneself to multiple measure and function study, obtained series to study positive result. Ever put forward to use a nucleus - technology of pattern plate of colloid of housing construction gel, preparation what housing layer ply and housing measure can adjust continuously is hollow tiny ball. On this foundation, it is pattern plate with colloid of poriferous and hollow high polymer, through controlling the site that material grows, preparation series is new-style compound colloid of the structure, if double carapace is hollow tiny ball and surface are had small dash forward copy gives birth to a structure.

In national science foundation appoint with the Chinese Academy of Sciences support energetically below, this task group gains new headway in the preparation respect of Janus colloid, formulated the new method of colloid of Janus of a kind of preparation, relevant achievement is published in the Angew.Chem.Int.Ed.2008 of the near future, 47, on 3973-3975) .

Control the composition of colloid and construction, gift its function, diagnosing like medical treatment, target to cure, can accuse to release, hot / fluid of acoustical insulation, intelligence, catalysis is detached, efficient pass a lot of domain such as filling of feeling, function to have applied perspective. This research involved the many across subject such as material, medicine, information, the sources of energy and environment.

Janus colloid is the colloid that shows one kind has double composition or quality, it is a kind of special functional sex colloid, the preparation means that its can charge is built is a crucial question. In the process that using colloid of Janus of Pickering latex preparation especially, colloid grain is in fluid - the whirl of fluid interface brought difficulty for its preparation. Researcher is to adsorption on Pickering latex interface body of 2 oxidation silica gel is in oily / water two-phase has group at the same time, implementation is lipophilic react with the graft of close water polymer, restrained the colloid whirl in the interface thereby, got at the same time organic / colloid of inorganic compound Janus. Carry series experiment research, formulated the new method of preparation Janus colloid. Pass location material of alternative compound function, preparation the Janus colloid of other composition and structure, extended the sort of functional colloid, for its function research and application laid a foundation.
