Due to their chemical differences, understanding the effect that the physical properties of the raw material confer on LCNFs is complex. This study aims at comprehending the impact that the physical properties and the chemical composition of the raw materials from Pinus radiata D. Don and Eucalyptus nitens Maiden have on the mechanical processes of fibrillation and the final properties of LCNFs. The anatomical, physical, and component differences of the fibers in the different fractions and species showed a non-effect on the longitudinal disintegration during the mechanical processes of fibrillation. In addition, the LCNFs produced from smaller fibers showed a smaller average width, with Eucalyptus nitens being the species that had smaller and more homogeneous nanofibrils. Nevertheless, the organization of the components (hemicellulose) from Pinus radiata on the surface of the fibrils, generates very hydrated and large fibrils and flocs, increasing the viscosities of the LCNF suspensions. A model was established between the intrinsic viscosity ( [ eta]) and aspect ratio ( p) of LCNFs ( rho[ eta] = 0.15p(1.68)) and delignified CNFs ( rho[ eta] = 0.031p(1.94)) that are independent of the pretreatments and the flexibility of the fibrils. Finally, the glass transition temperatures of lignin were not affected by physical changes in the raw material.This work was funded by the Agencia Nacional de Investigacion y Desarrollo (ANID)/Doctorado Nacional/2018-21181080, and projects FONDECYT No 1201042 and INNOMAT-H2 (MFA/2022/041) (Conselleria d'Innovacio, Universitats, Ciencia i Societat Digital).Springer-VerlagDepartamento de Ingeniería ElectrónicaDepartamento de Máquinas y Motores TérmicosEscuela Técnica Superior de Ingeniería Aeroespacial y Diseño IndustrialDepartamento de Ingeniería EléctricaEscuela Técnica Superior de Ingeniería Industrial Instituto Universitario de Investigación de Tecnología de los Materiales de la UPVEscuela Politécnica Superior de AlcoyGENERALITAT VALENCIANAAgencia Nacional de Investigación y Desarrollo de ChileFondo Nacional de Desarrollo Científico y Tecnológico, ChileRepositorio Institucional de la Universitat Politècnica de València Riunet20232023-05-01journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://riunet.upv.es/handle/10251/209796reponame:RiuNet.
