I want to graft polyethyleneglycol with aminated-silica nanoparticles to get a thin film. Any help would be greatly appreciated.
Grafting PEG or Aminated silica is pretty simple process.
You can supply a given solution of Aminated Silica with excessive dose of PEG.e.g for 0.5mmol Amincated Silica use 1mmol of PEG
Then you can characterise the obtained sample with FT-IR and AFM. Hope it will help you .
Dear all,
it is not really hard to find an answer to your question. A simple google search will produce pleinty of references. Attached files are exemples. Regards
