Nonlinear supramolecular polymers (NLSPs) exhibit the merits of reversibility and tunability, along with a unique topological structure. These features contribute to creation novel polymer species drive advancements in macromolecular engineering, making NLSPs promising direction for generating highly functional complex structures diverse applications. This article reviews recent advances NLSPs, including star, brush, hyperbranched, dendritic, cross-linked, cyclic polymers, from three key perspectives: controlled synthesis, tunable self-assembly, Firstly, direct indirect synthesis strategies used construct various are discussed. Subsequently, regulation methods self-assembly based on rationalized by considering internal structure parameters external environmental responses. Finally, comprehensive summaries potential applications biomedical materials, photoelectric self-healing degradable recycling as well catalytic provided. highlight versatility promise across industries. addresses scientific problems existing challenges this field. With rapidly growing area it is anticipated that they will shape future chemistry science, hold great research fields such chemical biomedicine, environment.

Abstract This study reports for the first time an innovative pH/magnetic dual-responsive hemicellulose-based nanocomposite hydrogel with a nearly 100% bio-based and biodegradable compositions. We synthesized pure Fe 3 O 4 magnetic nanoparticles (Fe MNPs) using co-precipitation, then engineering xylan hemicellulose (XH), acrylic acid (AA), polyethylene glycol diacrylate (PEGDA), MNPs to synthesize @XH-Gel), through free radical graft polymerization on natural XH in-situ doping initiated by ammonium persulfate/tetramethylethylenediamine (APS/TMEDA) redox system. Fourier transform infrared spectroscopy (FTIR), nuclear resonance ( 1 H-NMR), X-ray diffractometry (XRD), scanning electron microscopy energy dispersive spectrometer (SEM-EDS), Brunauer-Emmett-Teller (BET), dynamic light scattering (DLS), swelling gravimetric analysis, vibrating sample magnetometer (VSM) were employed analyze hydrogel’s chemical structures, surface morphologies, pH-responsive behaviors, responsiveness characteristics. The results indicate that @XH-Gel exhibited excellent dual pH magnetism. Furthermore, emphasis was placed in-depth analysis of response mechanism drug release control. Finally, we utilized this cutting-edge investigate controlled-release behavior two model drugs, Acetylsalicylic Theophylline , within simulated gastrointestinal tract. demonstrated exceptional controlled attributes, positioning it as potential carrier targeted delivery, particularly conditions.
