Carboxymethyl Cellulose Enhanced Polymeric Form Stable Phase Change Materials with Reversible Transparency for Energy Storage

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(42), P. 15623 - 15633

Published: Oct. 5, 2024

The rapid advancement of phase change material (PCM) has spurred numerous innovations, such as the use reversible optical properties solid–liquid materials in manufacturing devices. However, these often exhibit poor stability and low heat storage performance. Here, a method for producing cellulose-based gel (PCG) is proposed. addition carboxymethyl cellulose (CMC) significantly increased tensile strength postmelting, resulting remarkable 1131% increase compared with that CMC-free gels. Within this gel, poly(ethylene glycol) (PEG) embedded filler dual network cross-linked by hydroxyethyl methacrylate (HEMA) CMC, preventing leaks enhancing shape stability. maximum enthalpy values melting solidification reach 90.6 88.4 J/g, respectively. exhibits high degree haze effectively prevents glare, transparency changes ranging from about 25 to 78% during transitions. preparation process gels involves no toxic or harmful solvents, ensuring an environmentally friendly straightforward approach. This expands research opportunities intelligent devices, thermal energy management, beyond.

Small Methods, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 6, 2024

Abstract Magnetic nanoparticles have attracted great attention and become promising candidates in the biomedicine field due to their special physicochemical properties. They are generally divided into metallic non‐metallic magnetic nanoparticles, according compositions. Both of two types shown practical values applications, such as drug delivery, biosensing, bioimaging, so on. Research efforts devoted improvement synthesis strategies achieve with controllable morphology, diverse composition, active surface, or multiple functions. Taking high repeatability, programmable operation, precise fluid control, simple device account, microfluidics system can expand production scale develop desired features. This review will first describe different classifications followed by advancements microfluidic latest biomedical applications these nanoparticles. In addition, challenges prospects also discussed.
