About

The Instituto de Ciencia de Materiales de Madrid (ICMM) is an institute of the Consejo Superior de Investigaciones Cientificas (CSIC) (Spanish National Research Council) founded in December 1986, that belongs to the Area of Science and Technology of Materials, one of the eight Areas in which the CSIC divides its research activities.

 

Our mission is to create new fundamental and applied knowledge in materials of high technological impact, their processing and their transfer to the productive sectors at local, national and European scales (the true value of materials is in their use), the training of new professionals, and the dissemination of the scientific knowledge.

Functional Hybrid Nanopaper by Assembling Nanofibers of Cellulose and Sepiolite

M. Mar González del Campo, Margarita Darder, Pilar Aranda, Marwa Akkari, Yves Huttel, Alvaro Mayoral, Jefferson Bettini and Eduardo Ruiz-Hitzky

Functional heterofibrous hybrid materials are prepared in an integrative approach from aqueous dispersions of nanofibrillated cellulose and sepiolite by applying high shear homogenization and ultrasound irradiation. Both types of nanofibers remain physically cross?linked forming homogeneous and very stable high-viscosity gels that can be shaped as films and considered as “hybrid nanopapers” as well. The presence of sepiolite modifies the surface roughness of the films resulting from the casting process, which can be rendered hydrophobic, as the hydrophilic characteristics of both components resulted modulated. In addition, these fibrous hybrid systems can benefit from the properties provided by the two components, such as mechanical behavior, surface properties, and chemical reactivity. Moreover, further assembly of these hybrid nanopapers to other particulate solids, such as carbon nanotubes, magnetite, or ZnO nanoparticles, results in multifunctional hybrid nanopapers, opening a versatile way for developing other numerous organic–inorganic materials of interest in diverse applications.

Scheme of the procedures followed for dispersing CNF and sepiolite in water: A) homogenization by Ultra-Turrax high-shear disperser, and B) the same procedure followed by sonomechanical treatment. Pictures of the gels and the films resulting from each procedure are included in the scheme.
