oriented crystallization of polycarbonate by vapor grown carbon fiber and its application - pc sheet
As we all know, polyester (PC)
It is classified as amorphous polymer, and the pure PC crystal is very slow.
However, we recently found that in the presence of steam-grown carbon fiber, the crystals of PC accelerated significantly at around 200 °c (VGCF)
There's a lot of extra thick
Wall carbon nanotubes (MWCNT)structure.
In order to test the effect of VGCF accelerated Crystal
Graphite VGCF, carbon black and intermediate pitch-based carbon fiber (CF)
The crystal was evaluated.
In addition, polarized optical microscope observations were performed using PC including magnetic directional VGCF.
It was suggested that the surface of the ordered graphite structure from the VGCF or CF induced the axial directional crystals of the PC along the VGCF or CF.
In order to use CF to accelerate the directional crystal PC, by annealing the stacking structure of the PC sheet and the directional CF sheet at 200 °c, the PC sheet with the PC layer of the directional crystal surface was made
A pc sheet of the surface was successfully produced with axial crystals along the CF, and the delayed properties were shown through a polarized optical microscope.
