Modification of Pea Starch and Dextrin Polymers with Isocyanate Functional Groups
(MDPI, 2018-09)
Pea starch and dextrin polymers were modified through the unequal reactivity of isocyanate groups in isophorone diisocyanate (IPDI) monomer. The presence of both urethane and isocyanate functionalities in starch and dextrin ...
3D printing of customized all-starch tablets with combined release kinetics
(Elsevier, 2022-06-25)
[EN] Starch-based tablets with tailored releases were prepared by 3D printing using a hydrophobic drug. The importance of the origin of the excipient in the inks and tablets was analyzed. Besides, the effect of the geometry ...
Design of a Waterborne Polyurethane-Urea Ink for Direct Ink Writing 3D Printing
(MDPI, 2021-06-14)
In this work, polycaprolactone–polyethylene glycol (PCL–PEG) based waterborne polyurethane–urea (WBPUU) inks have been developed for an extrusion-based 3D printing technology. The WBPUU, synthesized from an optimized ratio ...
Morphological Analysis of Several Bamboo Species with Potential Structural Applications
(MDPI, 2021-06-28)
Bamboo constitutes a family of plants that are very promising and interesting as renewable materials for both large and small structure construction. To be used as an alternative to traditional materials; the understanding ...
Integral Valorization of Grape Pomace for Antioxidant Pickering Emulsions
(MDPI, 2023-05-08)
Full harnessing of grape pomace (GP) agricultural waste for the preparation of antioxidant Pickering emulsions is presented herein. Bacterial cellulose (BC) and polyphenolic extract (GPPE) were both prepared from GP. ...
Influence of Process Parameters in Graphene Oxide Obtention on the Properties of Mechanically Strong Alginate Nanocomposites
(MDPI, 2020-02-28)
Sodium alginate, a biopolymer extracted from brown algae, has shown great potential for many applications, mainly due to its remarkable biocompatibility and biodegradability. To broaden its fields of applications and improve ...
Superabsorbent bacterial cellulose spheres biosynthesized from winery by-products as natural carriers for fertilizers
(Elsevier, 2021-11-30)
[EN]Soil contamination, sustainable management of water resources and controlled release of agrochemicals are the main challenges of modern agriculture. In this work, the synthesis of sphere-like bacterial cellulose (BC) ...
Two different incorporation routes of cellulose nanocrystals in waterborne polyurethane nanocomposites
(Elsevier, 2016-03)
The renewability, availability and low-cost of eco-friendly cellulose nanocrystals (CNC), have gaining attention for nanocomposites preparation due to their unique properties in the nanoscale and their water dispersibility, ...
Shape-memory properties of crosslinked biobased polyurethanes
(2016-03-25)
Biobased crosslinked polyurethanes were synthesized and characterized as shape-memory polymers. Both the macrodiol and the diisocyanate were derived from renewable sources; the first one from castor oil, and the second one ...
Synthesis and characterization of polyurethanes with high renewable carbon content and tailored properties.
(2016-08-31)
Thermoplastic and cross-linked biobased polyurethanes with a renewable carbon content ranging from 78 to 98% were synthesized and characterized. The macrodiol and the diisocyanate used were derived from renewable source, ...
