Table 1.

Thermal properties of PAI/PANI/CB ternary blends with different compositions.

Composition	First Stage		Second Stage		Third Stage		Tg °C	Yc %	LOI %
	To/°C	Tmax/°C	To/°C	Tmax/°C	To/°C	Tmax/°C
0%	119	147	273	300	453	485	83.9	27	28
2.5%	128	164	295	321	472	499	87.5	28	29
5%	136	172	281	324	464	493	96.2	28	29
10%	156	175	292	321	463	492	99.3	31	30
12.5%	154	188	291	321	464	494	88.6	32	30

T_o is decomposition temperature at 5% loss; T_max is maximum decomposition temperature; the value of the limiting oxygen index (LOI) is calculated from Y_c at 700 °C.
