Question

What microcapsulation method can I use to encapsulate per-fluorocarbons in a silica based coating for slow release?

I need to find a method for slow release of vapours at ppb level and I am considering microcapsulation, which later would be impregnated on the silica based polymer.

    Dear Dorota, we are now approaching to a method to encapsulate per-fluorocarbons in liposomes, but actually I've not expertise on microencapsulation in silica . I'm sorry.

    You can use W/O/W microcapsulation method:
    1.organic phase:
    2. aqouse phase:
    3. Hemogenaite:
    4.centrifuge:

    Ionic gelation is probably the most suitable method of all.....

    Please give message mel and I can possibly help. I would need more information under NDA if necessary before coming up with a suggested method. I would be able to carry out the microencapsulation for you or sub-contract as appropriate.

    I will also say that the cross linking gelation is the most suitable method

    Dorota,
    Not sure if it's practical but there's a high vacuum system on first floor that could dry your samples onto the silica surface.
