Abstract
Polyparaphenylene (PPP) was pyrolyzed at 700 degrees C for increasing treat ment times in argon gas and for 6 h in different atmospheres (argon gas, hy drogen gas and under dynamic vacuum). Systematic analysis by X-ray diffract ion (XRD), Raman and infrared (IR) spectroscopies, and elemental analysis w ere performed in order to characterize the derived materials and to better understand the mechanisms of the PPP decomposition. A study of the porous s tructure completes this characterization. Thus, the thermal conversion of o rganic materials to carbon can be studied, especially at the beginning of t he polymer degradation. Important parameters for the application of these p olymers pyrolyzed as anodic materials for secondary lithium-ion battery app lication, such as the hydrogen content and the porous texture, are given in this work.
