Build-To-Specification Vanillin and Phloroglucinol Derived Biobased Epoxy-Amine Vitrimers
Genua, Aratz; Montes, Sarah; Azcune, Itxaso; Rekondo, Alaitz; Malburet, Samuel; Daydé-Cazals, Bénédicte; Graillot, Alain (MDPI, 2020-10-22)Epoxy resins are widely used in the composite industry due to their dimensional stability, chemical resistance, and thermo-mechanical properties. However, these thermoset resins have important drawbacks. (i) The vast ... -
Enhanced Biodegradability in Soil of Chicken Feather by Steam Explosion for Potential Application in Agricultural Biodegradable Plastics
Vadillo, Julen; Montes, Sarah; Grande, Hans-Jürgen; Verstichel, Steven; Almqvist, Jonna; Wrzesniewska-Tosik, Krystyna (MDPI, 2023-09-08)Feather waste is a major issue from an economic and environmental point of view. Even though there are already routes for the valorisation of feathers into fertilisers and feather meal, these are considered to have low ... -
Flexible Biocomposites with Enhanced Interfacial Compatibility Based on Keratin Fibers and Sulfur-Containing Poly(urea-urethane)s
Aranberri, Ibon; Montes, Sarah; Azcune, Itxaso; Rekondo, Alaitz; Grande, Hans-Jürgen (MDPI, 2018-09-21)Feathers are made of keratin, a fibrous protein with high content of disulfide-crosslinks and hydrogen-bonds. Feathers have been mainly used as reinforcing fiber in the preparation of biocomposites with a wide variety ... -
Fully Biodegradable Biocomposites with High Chicken Feather Content
Aranberri, Ibon; Montes, Sarah; Azcune, Itxaso; Rekondo, Alaitz; Grande, Hans-Jürgen (MDPI, 2017-11-09)The aim of this work was to develop new biodegradable polymeric materials with high loadings of chicken feather (CF). In this study, the effect of CF concentration and the type of biodegradable matrix on the physical, ... -
Functionalization of Cellulose Nanocrystals in Choline Lactate Ionic Liquid
Montes, Sarah; Azcune, Itxaso; Cabanero, German; Grande, Hans-Jürgen; Odriozola, Ibon; Labidi Bouchrika, Jalel (MDPI, 2016-06)Cellulose nanocrystals (CNCs) are valuable nanomaterials obtained from renewable resources. Their properties make them suitable for a wide range of applications, including polymer reinforcement. However, due to their highly ... -
Homogenization of Mutually Immiscible Polymers Using Nanoscale Effects: A Theoretical Study
Montes, Sarah; Etxeberria Lizarraga, Agustín ; Rodríguez, Javier; Pomposo Alonso, José Adolfo (Hindawi Publishing Corporation, 2008)A theoretical study to investigate homogenization of mutually immiscible polymers using nanoscale effects has been performed. Specifically, the miscibility behavior of all-polymer nanocomposites composed of linear-polystyrene ... -
Improved Thermal Insulating Properties of Renewable Polyol Based Polyurethane Foams Reinforced with Chicken Feathers
Aranberri, Ibon; Montes, Sarah; Wesołowska, Ewa; Rekondo, Alaitz; Wrzesniewska-Tosik, Krystyna; Grande, Hans-Jürgen (MDPI, 2019-12-03)In the present work, sustainable rigid polyurethane foams (RPUF) reinforced with chicken feathers (CF) were prepared and characterized. The bio-based polyol used to formulate the foams was obtained from castor oil. This ...
