Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

open access: yesAdvanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

Silicone Breast Implants as a Model System for Understanding Polymer Permeation in Soft Materials In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
Silicone breast implants are presented as a model system for understanding polymer permeation in vivo. Rather than representing material failure, “gel bleed” emerges from solution–diffusion transport‐mediated. By integrating polymer architecture, physicochemical transport, and biointerfacial processes, this review provides a unified framework that ...

An experimental investigation into the radiation-shielding performance of newly developed polyester containing recycled waste marble and bismuth oxide

open access: yesApplied Rheology, 2023
To obtain better radiation shielding, a new polyester has been made by the combination of 40 wt% of polyester and 30 wt% of fine waste marble mixed along with PbO (30–0) wt% and Bi2O3 (0–30) wt%.

Enhanced Mechanical Recycling of Polymer Mixtures by a Trifunctional Dynamic Crosslinker

open access: yesAdvanced Materials, EarlyView.
A self‐catalyzed, trifunctional dynamic crosslinker that incorporates three desired properties into one system and is compatible with reactive extrusion can compatibilize waste plastic mixtures containing high Tm polymers and impart the recycled mixtures with superior thermoset properties such as enhanced creep resistance and thermomechanical stability
