About

The Materials Science Institute of Madrid (ICMM) is a research centre of the Spanish National Research Council (CSIC) that belongs to the area Materia.

 

Our mission is to generate new fundamental and applied knowledge on materials and processes with added value, and their transfer to the productive sectors at the local, national and European scales. We are involved in the training of new professionals on materials research, and in the dissemination of the scientific knowledge.

 

We embrace diversity, and we defend inclusive science as the only possible one.

How to arrive


In memoriam Jorge Iribas (1966-2021)


El 16 de junio se nos ha ido, demasiado pronto, nuestro compañero Jorge Iribas Cerdá. Investigador Científico en el ICMM. Nos deja un importante legado científico, un código único para describir materiales a escala atómica con condiciones de contorno abiertas, y contribuciones en Física de superficies, materiales 2D, topología y magnetismo. Pero sobre todo nos deja un vacío muy grande como persona. Alma del grupo de teatro, amigo querido para todos por su carácter extrovertido y sus ganas de vivir.

Jorge, te echaremos de menos. Descansa en paz.

Hydrophobic composite foams based on nanocellulose-sepiolite for oil sorption applications

Sanguanwong A., Flood A.E., Ogawa M., Martín-Sampedro R., Darder M., Wicklein B., Aranda P., Ruiz-Hitzky E.



TEMPO (2,2,6,6-tetramethylpiperidin-1-oxyl)-oxidized cellulose nanofibers (CNF) were assembled to fibrous clay sepiolite (SEP) by means of a high shear homogenizer and an ultrasound treatment followed by lyophilization using three different methods: normal freezing, directional freezing, and a sequential combination of both methods. Methyltrimethoxysilane (MTMS) was grafted to the foam surface by the vapor deposition method to introduce hydrophobicity to the resulting materials. Both the SEP addition (for the normal and directional freezing methods) and the refreezing preparation procedure enhanced the compressive strength of the foams, showing compressive moduli in the range from 28 to 103 kPa for foams loaded with 20% w/w sepiolite. Mercury intrusion porosimetry shows that the average pore diameters were in the range of 30–45 µm depending on the freezing method. This large porosity leads to materials with very low apparent density, around 6 mg/cm3, and very high porosity >99.5%. In addition, water contact angle measurement and Fourier-transform infrared spectroscopy (FTIR) were applied to confirm the foam hydrophobicity, which is suitable for use as an oil sorbent. The sorption ability of these composite foams has been tested using olive and motor oils as models of organophilic liquid adsorbates, observing a maximum sorption capacity of 138 and 90 g/g, respectively.
