报告摘要：

Sepiolite-nanocellulose composite materials can be formed by mechanical high-shear homogenization and ultrasound treatments of water dispersions of the fibrous clay sepiolite of rheological grade and cellulose nanofibers (CNF) prepared by microfluidization and TEMPO treatment. In this way, the cellulose nanofibrils are assembled to the silicate nanofibers giving rise to homogeneous and stable biohybrid gels without appreciable syneresis effects. These gels can be processed by solvent casting as self-standing films showing an increase of the Young modulus from ca. 1 GPa for starting CNF to ca. 3 GPa for 20% content in sepiolite. These bionanocomposites can be also prepared by direct treatment of water dispersions of microcrystalline cellulose in the presence of sepiolite.  The resulting materials can be functionalized by further incorporation of nanoparticles of diverse nature such as MWCNT, magnetite or ZnO photoactive compounds.

Eduardo Ruiz-Hitzky is currently Ad Honorem Research Professor at the CSIC (National Research Council of Spain) working at the Materials Science Institute of Madrid (ICMM-CSIC) (http://www.icmm.csic.es/phbhmg/), where he has been Founder and First Director of the “New Architectures in Materials Chemistry Department” created in 2010.  

Professor Ruiz-Hitzky dedicated his research activities to the study of nanostructured materials being pioneer in various topics related to hybrid and biohybrid materials. He is author or co-author of more than 250 ISI web publications, with ca. 10,000 citations and h-index > 50, within the topics: Nanostructured Functional Materials; Hybrid, Biohybrid, Intercalation Compounds & Nanocomposites; Layered and Porous Inorganic Solids. Inventor or co-inventor of ca. 20 patents, some of them transferred to Industry. Supervisor of around 20 PhD Thesis and Editor-in-Chief and Associated Editor of the journals: Recent Patents in Nanotechnology and Current Nanoscience, respectively (since 2010).

He has been Member of the Direction Committee of the GEQI Group at the Spanish Royal Society of Chemistry, President of the Spanish Clay Society, and General Chair and Organizer of international conferences, including Annual Meetings of The American Chemical Society (ACS) in 2013-2018. He was in 2011 an Invited Professor at the Collège de France (Paris) and Senior Fellow at the National Laboratory of Nanotechnology, CNPEM (Campinas) in 2015, Invited Speaker at the Waseda University, Tokyo in 2012 and 2014, and Invited Lecturer at the MIT, Cambridge (USA), in 2017.

He has been recognized with several international awards including the AIPEA Medal (Tokyo, 2005), the STAS Prize (Académie Royale de Belgique, Belgium, 1976), the BRUYLANTS award (Université de Louvain, Belgium, 1977), the ICIDCA award (The Ministry of Sugar, Cuba, 1995), the National Academy of Sciences Award (Cuba, 2008 & 2017), the Guillaume Budé Medal (Collège de France, Paris 2011), the Josep Lleal Medal (Expoquimia, Barcelona 2011) and various distinctions from the CSIC.

He is also Honorary Member of the Spanish Clay Society (SEA) since 2018 and Distinguished Member of the Clay Minerals Society (CMS), being the recipient of the Marilyn and Sturges W. Bailey Distinguished Member 2019 Award, which is the highest distinction of this American Society.
