Wool/soy protein isolate membranes as separators toward more sustainable lithiu...
Serra, J. P.; Barbosa, J. C.; Silva, Maria Manuela; Gonçalves, Renato Ferreira; Uranga, J.; Costa, Carlos Miguel Silva; Guerrero, P.; de la Caba, K.Natural origin products exist in large quantities around the world and many times they are not properly exploited in order to realize their potential in novel applications, being often even discarded as by-products from other uses. In this study, wool and soy protein isolate (SPI) are proposed to develop separator membranes for lithium-ion batteries (LIBs), aiming toward a new generation of sustainable batterie...
Solid electrolytes based on i-carrageenan and different ionic liquids for susta...
Polícia, R.; Serra, J. P.; del Campo, Francisco Javier; Vilas-Vilela, J. L.; Correia, Daniela M.; Costa, Carlos Miguel Silva; Lanceros-Méndez, S.The increase in electronic waste (e-waste) is a significant global concern due to fast technological development in which products rapidly become obsolete. To mitigate this problem in the field of electrochromic devices, four different types of solid polymer electrolytes (SPEs) were developed based on iota-carrageenan, a water-soluble biopolymer, and 40 wt% concentration of different ionic liquids (ILs): 1-buty...
Influence of the inclusion of propylene carbonate electrolyte solvent on the mi...
Martins, Luis Amaro; Biosca, Laura Teruel; Gómez-Tejedor, José Antonio; Serra, J. P.; Correia, Daniela M.; Costa, Carlos Miguel SilvaThe influence of the inclusion of the organic solvent propylene carbonate (PC) in microporous membranes based on poly(l-lactic acid) (PLLA) and poly(vinylidene fluoride-co-hexafluoropropylene) P(VDF-HFP) has been studied based on its relevance for the application of those separator membranes in lithium-ion batteries. The membranes have been produced through solvent casting and characterized with respect to the ...

Serra, J. P.; Salazar, H.; Fidalgo-Marijuan, A.; Gonçalves, Renato Ferreira; Martins, Pedro M.; Lanceros-Mendez, S.; Costa, Carlos Miguel SilvaThe here presented experiments report on bi-functional iron oxide (Fe3O4)/poly (vinylidene fluoride-hexafluoropropylene) - PVDF-HFP porous membranes prepared through thermal-induced phase separation (TIPS) for As(III) and As(V) adsorption and posterior second life as a lithium-ion battery (LIB) separator considering a circular economy paradigm. The bi-functional membranes' physical-chemical properties, their ab...
Tuning magnetic response and ionic conductivity of electrospun hybrid membranes...
Hermenegildo, Bruno Filipe Costa; Correia, Daniela Maria Silva; Ribeiro, Clarisse Marta Oliveira; Serra, J. P.; Pérez, L.; Vilas-Vilela, José L.Electrospun membranes play an increasing role in tissue regeneration base on their suitable morphological features. The implementation of active response, such as magnetically responsiveness or piezo-ionic features can further improve tissue regeneration by better resembling varying microenvironment during cell culture. In this context, this work reports on the development of poly(vinylidene fluoride) (PVDF) or...
Ionic liquid modified electroactive polymer-based microenvironments for tissue ...
Hermenegildo, B.; Meira, R. M.; Díez, A. G.; Correia, Daniela Maria Silva; Ribeiro, S.; Serra, J. P.; Ribeiro, Clarisse; Pérez-Álvarez, L.The combination of electroactive polymers and ionic liquids (ILs) has been gaining much attention for tissue engineering. Thus, this work reports on the development of oriented electrospun fibers and films based on poly(vinylidene fluoride) (PVDF) and polyhydroxybutyrate-co-hydroxyvalerate (PHBV) blended with the IL choline acetate ([Chol][Ac]). The inclusion of IL into the polymer matrix induces a decrease in ...

Hermenegildo, B.; Meira, Rafaela Marques; Correia, Daniela Maria Silva; Díez, A. G.; Ribeiro, Sylvie Oliveira; Serra, J. P.; Ribeiro C.Polymer scaffolds are playing an increasing role in tissue engineering (TE), although there is still a need to improve their biomimicry of cellular microenvironments, by having smart scaffolds with an active response, which can improve tissue regeneration. This work reports on the novel combination of poly(lactic-co-glycolide) (PLGA) with the ionic liquid (IL) choline bis(trifluoromethylsulfonyl)imide ([Chol][T...
All printed soft actuators based on ionic liquid/polymer hybrid materials
Correia, D. M.; Fernandes, L. C.; Pereira, N.; Barbosa, J. C.; Serra, J. P.; Pinto, R. S.; Costa, Carlos Miguel Silva; Lanceros-Méndez, S.Soft actuators are increasingly being required for a variety of application ranging from robotics to biomedicine. This work reports on the development of printable materials for soft actuator applications based on ionic liquids (ILs) and a fluorinated polymer, poly(vinylidene fluoride) (PVDF). ILs sharing the same cation 1‑butyl‑3-methylimidazolium, [Bmim]+ and different anions (tricyanomethanide, [C(CN3)]−, di...
