2.1. Materials
CBT resin (CBT 100) is bought from Cyclics Corporation together with 0.6wt.% Tin-based catalyst (PC-4101).
The nano-TiO2 and nano-graphite particles, with an average diameter D of 50nm and 100nm respectively, are
provided by Degussa AG. All materials are dried at 100oC in the vacuum drying oven for 10h to remove the residual
moisture, which could interfere with the polymerization reaction of CBT oligomer. Samples with 0.5wt.% and
1wt.% nano-graphite and 1wt.% and 2wt.% nano-TiO2 are prepared.
2.2. Test method
The crystallization and melting behavior of pCBT are examined with differential scanning calorimeter (DSC) and
thermogravimetric analysis (TGA). The mass of samples is cut from bulk sample in the range of 7-15mg. Nitrogen
is used as the purge gas in the hot stage during all measurements and thermal treatments. Each sample is heated to
260
