Hi,
Preparing a sample (thin film of polymer or any other material) for TEM imaging is always demands lot of time and patience. Follow the steps mentioned below;
1. Prepare Resin mixture by mixing appropriate amount of (Eponate 12 Resin, Glycerol Polyglycidyl Ether), Dodecenyl Succinic Anhydride (DDSA), Nadic Methyl Anhydride (NMA), and 2, 4, 6 –Tris (dimethylaminomethyl)phenol (DMP-30).
2. Embed your sample (P3HT:PCBM blend) in epoxy mould and cure at 60 deg C for 12 h.
3. Ultra microtome the epoxy molded sample into thin membrane (
Thank you very much for Dr Suresha answer. Actually we have cured unsaturated polyester resin+nanoclay as filler. We want to cut this solid sample using microtome for TEM analysis, however microtome could not cut because the sample was brittle.
