Improved bleached eucalyptus kraft pulp-based tissue papers incorporating wet-s...
Matos, Marina; Carta, Ana M.; Pinto, Paula C.; Evtyugin, Dmitry V.Common tissue paper manufacturing trends aim at partial or total replacement of softwood pulp with hardwood pulp for its production, such as bleached eucalyptus kraft pulp (BEKP), in order to optimize the process and the final product properties such as softness. However, the use of a single type of hardwood fiber results in lower strengths of both wet and dry webs. To maintain necessary strength and desired pr...
Conversion of paper and xylan into laser-induced graphene for environmentally f...
Kulyk, Bohdan; Matos, Marina; Silva, Beatriz F. R.; Carvalho, Alexandre F.; Fernandes, António J. S.; Evtuguin, Dmitry V.; Fortunato, ElviraLaser-induced graphene (LIG) is a foam-like porous material consisting of few-layer graphene obtained by laser irradiation of a wide range of carbon-containing substrates. Among these, the ability to synthesize LIG from paper and other cellulose-related materials is particularly exciting, as it opens the door to a wide assortment of potential applications in the form of low-cost, flexible, and biodegradable dev...

Replacing Di(2-ethylhexyl) Terephthalate by Di(2-ethylhexyl) 2,5-Furandicarboxy...
Matos, Marina; Cordeiro, Rosemeyre A.; Faneca, Henrique; Coelho, Jorge F. J.; Silvestre, Armando J. D.; Sousa, Paula Andreia Fernandes deThe worldwide regulatory demand for the elimination of non-phthalate compounds for poly(vinyl chloride) (PVC) plasticization has intensified the search for alternatives. Concomitantly, sustainability concerns have highlighted sugar-based 2,5-furandicarboxylic acid as one key renewable-chemical for the development of several products, namely di(2-ethylhexyl) 2,5-furandicarboxylate (DEHF) plasticizer. This study ...
Co-Polymers based on Poly(1,4-butylene 2,5-furandicarboxylate) and Poly(propyle...
Matos, Marina; Sousa, Andreia F.; Mendonça, Patrícia V.; Silvestre, Armando J. D.Poly(ether ester)s (PEEs) represent a promising class of segmented co-polymers, nevertheless the synthesis of PEEs based on renewable 2,5-furandicarboxylic acid (FDCA) is still scarce. In this context, a series of poly(1,4-butylene 2,5-furandicarboxylate)-co-poly(poly(propylene oxide) 2,5-furandicarboxylate) co-polyesters with different composition of stiff poly(1,4-butylene 2,5-furandicarboxylate) (PBF) and so...
Biobased polyesters and other polymers from 2,5-furandicarboxylic acid: a tribu...
Sousa, Andreia F; Vilela, Carla; Fonseca, Ana C; Matos, Marina; Freire, Carmen S R; Gruter, Gert-Jan M; Coelho, Jorge F J; Silvestre, Armando J DMotivated by the general concern about sustainability and environmental issues, an intense search for renewable-based polymers has grown exponentially in recent years. This search definitely spotlighted polyesters derived from 2,5-furandicarboxylic acid, among other polymers, as some of the most promising, especially due to the resemblance of this renewable monomer to the well-known petroleum-based terephthalic...

One-pot synthesis of biofoams from castor oil and cellulose microfibers for ene...
Sousa, Andreia F.; Matos, Marina; Pinto, Ricardo J. B.; Freire, Carmen S. R.; Silvestre, Armando J. D.The use of renewable feedstocks in foam technology has created a worldwide demand for more sustainable materials. Castor oil is a vegetable oil, composed mainly of triricinoglycerol, a natural polyol, suitable for polyurethane foam production. In this study, castor oil and variable amounts of microcrystalline cellulose (MCC) fibers were used in a straightforward one-pot synthesis approach for the preparation of...
A New Generation of Furanic Copolyesters with Enhanced Degradability: Poly(ethy...
Matos, Marina; Sousa, Andreia F.; Fonseca, Ana C.; Freire, Carmen S. R.; Coelho, Jorge F. J.; Silvestre, Armando J. D.2,5-Furandicarboxylic acid is a promising renewable-based monomer essentially used in polymer synthesis to prepare renewable-based counterparts to petrochemical polyesters. In general, they are entirely based on renewable resources and have a myriad of very interesting thermal and mechanical properties; however, this study is the first to tackle their (bio) degradability, a worldwide-demanded property. To addre...
