Anthocyanin Hybrid Nanopigments from Pomegranate Waste: Colour, Thermomechanical Stability and Environmental Impact of Polyester-Based Bionanocomposites

Micó-Vicent, B.; Ramos, Marina; Viqueira, Valentín; Luzi, Francesca; Dominici, Franco; Terenzi, Andrea; Maron, Etienne; Hamzaoui, Mahmoud; Kohnen, Stephane; Torre, Luigi; Jimenez, Alfonso; Puglia, Debora; Garrigós, María Carmen (MDPI AG, 2021-06)

[EN] In the present work, anthocyanin (ACN) hybrid nanopigments were synthetized by using a natural pomegranate dye (PD) and calcined hydrotalcite (HT) and montmorillonite (MMT) nanoclays. A wide colour gamut was obtained ...
Effect of Lemon Waste Natural Dye and Essential Oil Loaded into Laminar Nanoclays on Thermomechanical and Color Properties of Polyester Based Bionanocomposites

Micó-Vicent, B.; Viqueira, Valentin; Ramos, Marina; Luzi, Francesca; Dominici, Franco; Torre, Luigi; Jiménez, Alfonso; Puglia, Debora; Garrigós, Maria Carmen (MDPI AG, 2020-07)

[EN] In this work, polyester-based nanocomposites added with laminar nanoclays (calcined hydrotalcite, HT, and montmorillonite, MMT) loaded with lemon waste natural dye (LD) and essential oil (LEO) were prepared and ...
Evaluating the Graininess Attribute by Visual Scaling for Coatings with Special-Effect Pigments

Perales, Esther; Micó-Vicent, B.; Huraibat, Khalil; Viqueira, Valentín (MDPI AG, 2020-04)

[EN] In our society, objects' visual appearance is an essential factor because it allows us to recognize and differentiate one object from another. In different industrial sectors like cosmetics, textiles and automotive, ...
Halloysite and Laponite Hybrid Pigments Synthesis with Copper Chlorophyll

Micó-Vicent, B.; Perales Romero, Esther; Jordán-Núñez, Jorge; Viqueira, Valentín (MDPI AG, 2021-06)

[EN] Sustainable and green materials have been studied in dye and pigment productions to reduce their environment impacts from being produced and applied. Although natural dyes are an excellent choice to move from agrowaste, ...
Maximization of FDM-3D-Objects Gonio-Appearance Effects Using PLA and ABS Filaments and Combining Several Printing Parameters: "A Case Study"

Micó-Vicent, B.; Perales Romero,Esther; Huraibat, Khalil; Martínez-Verdú, F.; Viqueira, Valentín (MDPI AG, 2019)

[EN] In order to consider 3D objects from suitable Fused Deposition Modelling (FDM) printers as prototypes for the automotive sector, this sample must be able to reproduce textural effects (sparkle or graininess) or metallic ...
Mejora de las propiedades térmicas y ópticas de una bioresina empleando Nanopigmentos con colorantes naturales
