Abstract

A nanocomposite-based 1:2 demultiplexer is presented, leveraging surface-grafted poly(methacrylic acid) (PMAA) brushes embedded with in situ-fabricated cadmium sulfide (CdS) nanoparticles. The presented nanocomposite design synergizes electronic properties of semiconducting CdS with the unique polymer brushes architecture, enabling precise photo-induced signal routing. The PMAA brushes were synthesized via surface-initiated atom transfer radical polymerization (ARGET-ATRP), followed by the in-situ generation of CdS nanoparticles through a controlled chemical precipitation method, resulting hybrid structure with uniform CdS nanoparticle distribution. Characterization techniques, including atomic force microscopy (AFM), secondary ion mass spectrometry (SIMS), electron microscopy (SEM) and photoelectrochemical analysis, confirm the successful integration and functional behavior of the obtained PMAA-CdS system and using it for building of 1:2 demultiplexer. Our nanodevice enables the conversion of optical signals into electrical signals, so it can be successfully used to process information at the molecular level.

期刊介绍： European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas: Polymer synthesis and functionalization • Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers. Stimuli-responsive polymers • Including shape memory and self-healing polymers. Supramolecular polymers and self-assembly • Molecular recognition and higher order polymer structures. Renewable and sustainable polymers • Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites. Polymers at interfaces and surfaces • Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications. Biomedical applications and nanomedicine • Polymers for regenerative medicine, drug delivery molecular release and gene therapy The scope of European Polymer Journal no longer includes Polymer Physics.
