摘要: In the present work evolution of physical and mechanical properties papers nanopapers is studied. Handsheets made eucalyptus fibres reinforced with 0, 25, 50, 75 100 wt% nanofibrillated cellulose (NFC) content were fabricated using a Rapid Kothen-like equipment. The obtained physical- mechanically-characterized. results showed significant increase in density reduction porosity samples during their transition from paper to nanopaper; besides, more transparent smoother than normal papers. These changes where evident increasing amounts NFC. Regarding properties, NFC improved strength rigidity 228 317 %, respectively, comparison nanopaper was linear relation amount NFC, which means that ultimate tensile mainly dependant on nanofibril failure.
