After the oxidation, G0 and G00 became similar, indicating that the particle network in the dispersion was significantly disrupted. The number and volume averaged particle size of the oxidized CF are 0.67 lm and 1.25 lm respectively, similar to that of hydrolyzed CF. About 92% of the oxidized CF can be filtered through a 0.7 lm filter and has a number and volume averaged size of 250 and 310 nm, respectively.
