Pbo synthesis
SpletPBO fibers have tensile strengths and moduli as high as 5.6 and 352 GPa, respectively, and specific moduli and strength 9.4 and 9.0 times that of steel. Both PBO and PBZT have high thermal stability and do not exhibit softening behavior prior to thermal degradation, which occurs above 600 8C in air and nearly 700 8C in an inert atmosphere. SpletFor PBO/ SWNT (90/10) composition, 0.47 g of purified HiPco tubes (SWNT) was added to the mixture. The sequence of steps and polymerization conditions remain the same as those for PBO/ SWNT (95/5) composition. Intrinsic viscosity values of PBO and PBO/SWNT (90/10) were 12 and 14 dL/g, respectively. PBO and PBO/SWNT fibers were dry-jet wet …
