| dc.description.abstract | A series of PBCs was successfully synthesized through FeCl3 initiated chemical oxidative polymerization at different concentrations (M) of PY ranging 0.5 to 2.0 in presence of OBC. Formation of OBC, PPY and PBCs was ascertained through FT-IR spectra. SEM revels show porous morphology of PBCs. TG reveals multistep decomposition of OBC, whereas, PPY and [III] were decomposed in a single step. OBC, PPY and [III] has shown common TG onset at 200 oC with decreasing order of % Wr ranging 93.58 to 86.7. Moisture content of [III] (1.8%) was significantly controlled due to modification of PPY (4.75%) with OBC. The rate of expulsion of moisture by [III] (15.3 μg/min) was also controlled over PPY (7.5 μg/min). Maximum degradation of OBC was appeared @ 17.8 μg/min at 518 oC that was relatively low for PPY (@ 64μg/min). Modification of PPY with OBC has liberated [III] with maximum decomposition @ 47.6 μg/ min. This indicates the significance of OBC towards modification in thermal stability of PPY | en_US |
