In this study, we integrated organic phase change materials, decanoic acid (DA) and palmitic (PA), into bio-based samples made from sodium alginate (SA) flax fiber (FF). We also synthesized conductive polypyrrole (PPy) coating through in situ polymerization to create two thermal energy storage conversion systems with distinct temperatures (32 °C 63 °C). The PPy exhibited uniform polymerization, resulting electrical conductivity (1.52 ± 0.07 S/m) (0.453 0.02 W/mK). sponge, similar the plain had a porous microstructure (85 % porosity) that allowed successful impregnation of 60 74 DA PA, outstanding properties. Specifically, sponges PA achieved enthalpies 100.98 J/g 154.52 J/g, respectively. DA/PPy@Sponge demonstrated exceptional durability after cycling tests. Furthermore, sample efficiently converted along path, making it suitable for storing generated heat as both sensible latent heat, well capturing solar energy. Overall, developed materials offer shape stabilization, high capacity, efficient electric/photo-to-thermal These attributes make them promising candidates diverse applications harvesting, storage, management electronics, buildings, transportation, other relevant fields.

Graphene oxide modified sodium alginate/polyethylene glycol phase change material hydrogel scaffold composite with photothermal temperature control for potential bone tissue regeneration

Journal of Materials Research and Technology, Journal Year: 2024, Volume and Issue: 30, P. 2446 - 2457

Published: April 3, 2024

The challenge of precisely regulating temperature during the photo-thermal bone promotion remains unresolved. Phase change material (PCM), capable undergoing a phase transition at specific temperature, offers solution by photothermal regulation through storage and release heat. This study incorporated biocompatible polyethylene glycol (PEG) with points as PCM. A hydrogel scaffold was then synthesized semi-crosslinking PEG calcium-ion-chelated sodium alginate (SA) acting structural framework. Additionally, newly developed graphene oxide (GO) modified composite scaffolds (GO-PHSC), featuring 0.5 wt% GO, not only demonstrated outstanding conversion efficiency an optimal (42.2 °C) but also exhibited desirable values for latent enthalpy (100 J/g) heat recovered (LHR) (93.3%). Moreover, form-stability test PCM scaffolds' exceptional resistance to leakage maintenance shape stability even elevated temperatures (70 °C). Beyond achieving passive control in therapy, experimental findings highlighted that hydrogel, incorporating calcium ions met various requirements such physicochemical properties, microstructure, mechanics, mineralization, biocompatibility, cell affinity. These collective attributes suggest GO-PHSC emerges promising candidate temperature-controlled therapy regeneration.
