Preparation and optimization of grafted hydroxyethyl cellulose, polypyrrole, and nitrogen-doped carbon quantum dots bionanocomposites for electrical, optical, and photoluminescence multicoloring applications.

The major objective of this research revolves around the integration of polypyrrole (PPy) and various concentrations of nitrogen-doped carbon quantum dots (N-CQDs) into a polyacrylamide (PAm)-grafted hydroxyethyl cellulose (gHEC) to produce gHEC@PPy@N-CQDs bionanocomposites that possess environmentally sustainable properties. The intercalation and uniform distribution of N-CQDs inside the gHEC@PPy matrix have been demonstrated through the analysis of data obtained from X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The samples underwent analysis using thermogravimetric analysis (TGA and DTG) as well as scanning and transmission electron microscopy.

Facile assembly of flexible quaternary SnO/SrSnO/FeO/PVDF nanocomposites with tunable optical, electrical, and magnetic properties for promising magneto-optoelectronic applications.

Facile assembly, co-precipitation, and drop casting procedures have been used to construct SnO/SrSnO/FeO/PVDF flexible nanocomposites. SnO/SrSnO/FeO nanocomposites (TSF NCs') have been successfully incorporated into polyvinylidene fluoride polymers (PF), according to the microstructural exploration of the systems, which was revealed by XRD, EDX, and ATR-FTIR analysis. The FESEM and cross-section areas demonstrated that the addition of TSF NCs' to PF porous material enhanced its surface characteristics and decreased its surface roughness.
