Group

The Macromolecular and Lignocellulosic Materials Group , a research team at the Department of Chemistry , University of Aveiro , develops its activity within the framework of CICECO (Centre for Ceramic and Composite Materials), a Portuguese centre of excellence (Associate Laboratory) in Materials Science. Our research activity is centred within the scope of both lignocellulosic chemistry/technology and polymer science.

The group is now composed of 6 permanent staff and, on average, of some 20 post-graduate students and is involved in several research projects , in cooperation with National and European Universities, Research Centres and Industry.

The publication scores of the Macromolecular and Lignocellulosic Materials Group in the last 10 years include about 200 papers in SCI (Science Citation Index) journals, 4 patents and more than 200 papers or abstracts in conference proceedings. 9 Doctorate theses and 15 Master theses were concluded in our group.

Staff members participate actively in the editorial boards of Holzforschung , Journal of Wood Chemistry and Technology, Cellulose Chemistry and Technology, Polymer International and O Papel as well as in the Scientific Commissions of many international conferences, among which the International Symposium on Wood, Fibre and Pulping Chemistry (ISWFPC) and European Workshop on Lignocellulosics and Pulp (EWLP) and several international Polymer Conferences . The fifth EWLP was organized in Aveiro by our group in 1998.

The Macromolecular and Lignocellulosic Materials Group is a member of EFPRO – European Fibre and Paper Research Organizations.

Research activity

The Macromolecular and Lignocellulosic Materials Group activity is centred on the study of the chemical structure of lignocellulosics (including wood, cork, biomass and related biopolymers), the chemistry and technology associated with its industrial transformation (namely into pulp and paper) and the development of new materials and products derived from lignocellulosics and their components, as well as from industrial by-products, within the context of the forest-based biorefinery concept.

Particular attention is now devoted to postgraduate training and research on “polymers derived from renewable resources”, within the scope of a newly created platform involving several national industrial partners – ID PoR .

The main current research lines include:

•  Chemicals and materials from by-products of Eucalyptus globulus kraft and sulphite pulping processes – forest-based biorefineries

•  The improvement of Eucalyptus globulus sulphite pulping and bleaching processes

•  The behaviour of wood polysaccharides during Eucalyptus globulus kraft pulping

•  Polyoxometalate catalyzed delignification / oxidative processes

•  Nanostructured coatings for paper applications

•  Materials derived from bacterial cellulose

•  Materials from chemically modified cellulose fibres and polysaccharides, including chitosan

•  New hybrid materials based on cellulose fibres and mineral nanoparticles

•  Polymers from renewable monomers (furan, suberin, lignosulphonates)

•  Polymer-based nanocomposites

The Macromolecular and Lignocellulosic Materials Group has strong ties with other research teams in the Department of Chemistry of the University of Aveiro, namely with the Chemical and Biochemical Engineering, Food Science and Biochemistry and Mass Spectrometry groups, as well as with colleagues in the field of Nuclear Magnetic Resonance, Nanosynthesis and Nanomaterials. The group has also a close collaboration with RAIZ, the research centre of Portucel-Soporcel group, located near Aveiro.
