T. Komatsu et M. Samejima, Balloon-shaped graphitic-carbon material induced by shock-compression of dehydrochlorinated poly(vinylidene chloride), J MAT CHEM, 8(12), 1998, pp. 2725-2728
Shock-compression of dehydrochlorinated poly(vinylidene chloride) at 15 GPa
and 6500 K produced a small portion of balloon-shaped graphitic-carbon mat
erial mixed with a large proportion of graphite and diamond. The size and t
hickness of the various balloon particles were ca. 40-300 nm and 4-6 nm, re
spectively. The balloon-shaped material is presumably a by-product from a c
arbon source fragmented under shock-compression and would not be related to
the high yield of diamond.
