Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Water Absorption and Thickness Swelling Properties of Silica Aerogel Infused Sugar Palm Fiber/Polyester Composites

open access: yesInternational Journal of Recent Technology and Engineering, 2019
Using natural fibres as reinforcements in composites provides an inexpensive green alternate to its synthetic counterpart. In a similar scope, to enhance the usability of sugar palm fibres (SPF) in composites, various weight percentages (1% to 5%) of silica aerogel (SA) were infused in SPF reinforced unsaturated polyester composites.

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites

open access: yesAdvanced Functional Materials, EarlyView.
Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.
