The substitution of fossil resources by alternatives derived from biomass is a reality that is taking on a growing relevance in the chemical and energy industries. In this sense, fats, oils, and their derived products have become indispensable inputs due to their broad functional attributes, stable price and sustainable character. Acrylated vegetab...

Bio‐based photocurable polymers are increasingly demanded as environmentally friendly materials for advanced applications. Together with functional fillers, represent a next step for the generation of functional and active smart materials, compatible with additive manufacturing technologies. This work reports on, acrylated epoxidized soybean oil (A...

Mismanagement, pollution and excessive use have depleted the world’s water resources, producing a shortage that in some territories is extreme. In this context, the need for potable water prompts the development of new and more efficient wastewater treatment systems to overcome shortages by recovering and reusing contaminated water. Among the water...

Composites based on Chitin (CH) biopolymer and Metal‐Organic Framework (MOF) microporous nanoparticles have been developed as broad scope pollutant absorbent. Detail characterization of the CH/MOF composites reveals that the MOF nanoparticles interact through electrostatic forces with the CH matrix inducing the CH´s macro‐pores compartmentalization...

Magnetic materials are among the most commonly required for a wide variety of applications. Further, their fabrication and implementation by means of additive manufacturing technologies are also getting increasing attention. In this context, photocurable magnetic materials based on polyurethane acrylated (PUA) polymer and different magnetic particl...

Photocurable thermochromic and humidity responsive materials based on polyurethane acrylated (PUA) and bis(1-butyl-3-methylimidazolium) tetrachloronickelate ([Bmim]2[NiCl4]) ionic liquid (IL) have been prepared with varying IL content up to 40 wt.% within the polymer matrix. The influence of IL content on the photopolymerization process, morphology...

The increased demand of electronic devices promotes the development of advanced and more efficient energy storage devices, such as batteries. Lithium-ion batteries (LIBs) are the most studied battery systems due to their high performance. Among the different battery components, the separator allows the control of lithium ion diffusion between the e...

Photopolymerizable materials are commonly used in the industry for a long time, being extended their use in adhesives, coatings, paint and printing ink industries, composite materials, or even in the food industry. Their use in biomedical industry was until recently quite limited to acrylic derivatives used for dental restauration. However, the inc...

Taking into consideration environmental issues and additive manufacturing technologies, the development of advanced UV curable polymers and polymer composites is an area of increasing interest. In this scope, polyurethane acrylate (PUA) composites with Indium Tin Oxide (ITO) were produced in order to tune morphology, optical, thermal, mechanical an...

Photopolymerization or UV curing represents a fast and solvent-free technique to obtain polymer-based composites, being one of the main methods used in lithographic processes, surface coatings and the manufacture of integrated circuits. This work reports on the development of UV curable barium titanate/polyurethane acrylate (BaTiO3/PUA) composites...

Polymer-based composites are increasingly used for the development of stimuli responsive smart and multifunctional materials. Most of those materials are obtained from solvent-based processes, but the use of solvents represents usually induce non-desirable environmental issues and waste generation. Thus, UV-curable materials, processed at room temp...

The three-dimensional (3D) printing technology is changing the modern manufacturing of many pieces due to its versatility, immediacy and reduced cost. Thus, stereolithography (SLA), as one 3D printing technology, is becoming an important method to construct small pieces and, therefore, new materials used for it are still nowadays under study. SLA h...

Fabrikazio gehigarriak metodo tradizionalekin alderatuta abantaila ugari ditu, hala nola diseinu askatasuna, pertsonalizazioa, egitura konplexuak fabrikatzeko gaitasuna edota prototipoen sorrera azkarra. 3D inprimaketa teknologietan material ezberdin ugari erabiltzen badira ere, polimeroak dira gailentzen direnak, beraien aldakortasuna, kostu baxua...
