α‐Methoxy Benzaldehyde Based Photopolymers as a Promising Toolbox for Architected Carbon

open access: yesMacromolecular Rapid Communications, EarlyView.
The photo‐induced Diels–Alder step‐growth polymerization of difunctional α‐methoxy benzaldehyde and bismaleimide precursors affords photopolymers shaped into microspheres that are ideally suited for the formation of tailored carbon geometries. Stable carbonized microspheres with close to 60% char yield and 33% shrinkage can be readily formed at a ...

Polymerization‐Induced Direct Photolithography of Quantum Dots

open access: yesMacromolecular Rapid Communications, EarlyView.
We present a comprehensive overview of photochemical polymerization strategies for direct lithographic patterning of colloidal quantum dots (QDs). Reaction mechanisms are categorized by functional group type, and their application is discussed in terms of pattern fidelity, photostability, and environmental robustness, highlighting the potential of ...

Degradation strategies for structural characterization of insoluble synthetic polymers by mass spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract With the advent of soft ionization techniques such as electrospray (ESI) and matrix‐assisted laser desorption/ionization (MALDI) to produce intact gas‐phase ions from nonvolatile macromolecules, mass spectrometry has become an essential technique in the field of polymeric materials.

Mechanical and hydrophobic properties determination of epoxy/ignimbrite/pine waste composites

open access: yesPolymer Composites, EarlyView.
Schematic diagram of production epoxy/ignimbrite/pine waste composites. Abstract In this study, for the first time, composites have been prepared using ignimbrite and pine waste in epoxy matrix for the restoration of civil architecture examples in Anatolia (Turkiye).

Sustainable two‐step functionalization of carbon fibers (CFs) with polyethyleneimine and investigation of curing kinetics in composite materials

open access: yesPolymer Composites, EarlyView.
We followed the functionalization steps outlined in the figure to obtain carbon fibers (CFs) functionalized with branched polyethyleneimine (b‐PEI). The entire process was carried out under mild conditions, including plasma activation and low‐temperature heating, using an eco‐friendly solvent (water).
