“…In addition, surface functionalization of inorganic substrate materials can also be accomplished by a one‐step KF reaction. [ 115–117 ] The preparation of functional polymers with AIE properties through KF reaction was first presented by Long et al. [ 118 ] They showed that KF reaction can be used as a clean coupling reaction for fabrication of functional luminescent copolymers with economical, green, and high‐yield.…”

As the core of polymer chemistry, manufacture of functional polymers is one of research hotspots over the past several decades. Various polymers are developed for diverse applications due to their tunable structures and unique properties. However, traditional step‐by‐step preparation strategies inevitably involve some problems, such as separation, purification, and time‐consuming. The multicomponent reactions (MCRs) are emerging as environmentally benign synthetic strategies to construct multifunctional polymers or composites with pendant groups and designed structures because of their features, such as efficient, fast, green, and atom economy. This mini review summarizes the latest advances about fabrication of multifunctional fluorescent polymers or adsorptive polymeric composites through different MCRs, including Kabachnik–Fields reaction, Biginelli reaction, mercaptoacetic acid locking imine reaction, Debus–Radziszewski reaction, and Mannich reaction. The potential applications of these polymeric composites in biomedical and environmental remediation are also highlighted. It is expected that this mini‐review will promote the development preparation and applications of functional polymers through MCRs.

“…The results of TGA and DSC confirmed that the addition of ZnO nanorods within a concentration range (0, 0.5, 0.7, 1 and 3 wt%) enhanced the thermal stability of PS and the most thermally stable nanocomposites were obtained at 1 wt% of ZnO nanorods by a delay of 10°C in thermal degradation. Karimabad et al [20] mentioned that silicon dioxide (SiO2) nanoparticles, synthesized by sol-gel process and then added to the PS polymer matrix, exhibited good performance in flame retardancy. The investigation of TGA showed that the thermal decomposition of the PS-SiO2 composite was shifted towards a higher temperature (370 °C) due to the presence of tin oxide.…”

In this study, different nano sizes of lead oxide particles are prepared using high-speed planetary ball milling over a range of grinding times (15, 30, 60 and 120 minutes). The characterization of the prepared nanoparticles is carried out using X-ray diffraction (XRD), transmission electron microscopy (TEM), dynamic light scattering (DLS) and Fourier Transform-Infrared spectroscopy (FTIR). The XRD pattern reveals a phase transition from β-PbO to α-PbO with increasing the milling time. The PbO particles milled for 30 and 60 minutes and termed PbO(A) and PbO(B), respectively, are chosen for this research as they display less agglomeration and achieve nano sizes of 78 and 52 nm, respectively. The following stage utilizes PbO(Bulk), PbO(A) and PbO(B) as fillers and incorporates them independently into PS with a concentration of 10, 15, 25 and 35 wt % using roll mill mixing and compression molding techniques to create a novel polystyrene composite (PS/PbO). PS/PbO composites were then characterized by XRD, which shows a decrease in the phase percentage of PS to α-PbO with increasing PbO content. Extensive research of thermal characteristics employing thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) enables the evaluation of decomposition rates and activation energies. The analysis reveals that the addition of bulk and nano PbO particles shifts Tini and T50% to higher temperatures, and reduces the decomposition rate as well as the activation energy. This means that the thermal stability of PS is increased, especially using a small PbO nano size. This study emphasizes the role of particle size in enhancing the thermal properties of polystyrene, allowing it to withstand elevated temperatures in applications such as coating, insulation and radiation shielding.
