| Abstract | Cellulose fibers (CFs) and carbon nanotubes (CNTs) were successfully developed on polyurethaneสsubstrateสas a flexible composite paper. With small amount of CNTs, the composite was prepared byสa suction filtration method. The existence of CNT additive in cellulose matrix was investigated based onสthe correlation of mechanical properties, thermal stability, and electrical properties. Although theสhighly transparent cellulose sheets impregnated with polyurethane were successfully fabricated, theสlow transmittance was obtained as the increasing of CNT additive. However, the dielectric properties ofสcomposite were enhanced with an addition of CNTs in the composite paper. The electrical conductivityสwas increased from the insulator to 4.91ส_ส10-4สS_cm-1สat small amount of CNTs of 5 wt%. In addition, the minimal amount of CNTs of 1.5% showed the transmittance of 35%, adequate dielectric constant, and the conductivity of 5.59 _ 10-7สS_cm-1. The role of CNTs with well distribution presents as a polar cluster of well-defined electrically charge in cellulose composite. |
