Curaua and eucalyptus nanofibers films by continuous casting: Mechanical and thermal properties

Carbohydrate Polymers, 2018
A wide variety of new green materials such as curaua leaf fibers (CLFs) has potential applications in nanotechnology. This study aims to investigate the thermomechanical properties and morphological structure of cellulose nanocrystals (CNCs) and cellulose nanofibrils (CNFs) films obtained by continuous casting. The CNCs were obtained by acid hydrolysis

Modificação das propriedades das fibras de curauá por acetilação Modification of the properties of curauá fibers by acetylation

Revista Brasileira de Engenharia Agrícola e Ambiental, 2011
Nos compósitos cimentíceos as fibras vegetais podem sofrer vários graus de degradação quando expostas ao ambiente alcalino. O meio alcalino degrada os componentes macromoleculares das fibras, principalmente pela solubilização da lignina e a desfibrilação
