Facile synthesis of two-photon absorbing polymers through radical copolymerization

open access: yeseXPRESS Polymer Letters, 2007
A two-photon absorbing polymer has been prepared through radical copolymerization of methyl acrylate and a synthesized monomer containing a two-photon absorbing chromophore (E,E,E)-1,3,5-tristyrylbenzene (1), under conventional radical polymerization ...

Multifunctional Gelatin‐Based Smart Films Integrating Thermochromic Encryption, Temperature‐Regulated Photothermal Management, Reprocessability, and Biodegradability for Sustainable Applications

open access: yesAdvanced Science, EarlyView.
Multifunctional gelatin films synergizing thermochromic encryption, self‐regulating photothermal management, and closed‐loop recyclability offer sustainable solutions for intelligent packaging. ABSTRACT Multifunctional gelatin‐based smart films are engineered by incorporating hyperbranched polyglycerol (HBPG) as a plasticizer, dialdehyde β‐cyclodextrin

Universal Solvent Escape Strategies for Efficient Curing of Hydrogen‐Bond‐Rich 3D Printing Inks

open access: yesAdvanced Science, EarlyView.
This study developed a new 3D printing method for hydrogen‐bonded polymers by combining solvent replacement, nanoparticles, and optimized printing paths. This allows fast, precise scaffold fabrication. The scaffolds can be easily customized and release therapeutic agents slowly through protonation, enabling personalized bone, blood vessel, and nerve ...
