Special Issue Information

Dear Colleagues,

With the rapid development of science and technology and the rapid growth of the global population, the intensification of industrial activities has significantly enhanced energy consumption and caused serious environmental issues. Polymers are a class of important materials with applications in energy storage and conversion as well as environmental remediation because of their excellent processability; low cost; plentiful functional groups; and appealing electronic, catalytic and mechanical properties. Nanostructured polymers, including nanofibers, nanorods, nanoparticles, nanoplates, etc., have attracted considerable attention owing to their enhanced performance resulting from their large surface areas, increased accessible active sites and the convenient pathways for charge transfer.

This Special Issue focuses on the latest research advances in the design and preparation of nanostructured polymer-based materials, including their composites and carbonized materials, and their energy and environmental applications. These applications include rechargeable lithium batteries, supercapacitors, microbial fuel cells, thermoelectric generators, electrocatalysts for oxygen reduction, photocatalysts for visible-light hydrogen evolution, pollutant removal from wastewater and soil, pollutant degradation, membrane separation, gas separation, and CO2 capture, among others. Other topics of interest are also welcome if the intended research topics generally fit into the category of the preparation and characterization of nanostructured polymer-based materials for energy and environmental applications. We hope that these contributions will provide new insights into the design and preparation of high-performance polymer materials for addressing the rising energy consumption and environmental pollution.

Bisphenols (BPs) are a class of endocrine disruptors widely existing in the environment. They have a great impact on human health owing to their environmental endocrine disrupting effects, chronic toxicity, neurotoxicity, cytotoxicity and genetic toxicity. In this paper, an on-line packed fiber solid phase extraction (PFSPE) coupling with column-switching HPLC-FLD determination method was developed for the determination of eight BPs in drinking water. The poly (dibenzo-18-crown-6-ether)/polystyrene composite nanofibers (PDB18C6/PS) were prepared by electrospinning and used as an adsorbent for the on-line PFSPE column. The on-line PFSPE-HPLC equipment contained a dual ternary pump and a switching valve to enable enrichment, purification, and analysis directly in the system. The results showed that the proposed on-line PFSPE-HPLC-FLD method realized the simultaneous separation and detection of eight BPs: BPF, BPE, BPA, BPB, BPAF, BPAP, BPC and BPZ. The curves of the target analytes were prepared with good correlation coefficient values (r2 > 0.998) in the range of 50–1000 pg/mL. The limit of detection (S/N = 3) was 20 pg/mL, the limit of quantitation (S/N = 10) is 50 pg/mL. The recoveries of eight BPs were 94.8–127.3%, and the intra-day precisions (RSD) were less than 10%. The PFSPE column made of the PDB18C6/PS composite nanofibers has stable properties and can be reused at least 200 times. In the detection of drinking water samples, BPZ was detected in nearly 80% of drinking water samples, and BPA, BPAP, BPF and BPAF were also detected in some water samples. This high level of integration and automation was achieved in pretreatment of eight BPs from water samples. The proposed simple, rapid, and practical method has been successfully applied to the detection of eight BPs in drinking water, which can provide powerful technical support for drinking water quality and safety monitoring.

Advanced polymer dielectrics with high energy density at elevated temperatures are highly desired to meet the requirements of modern electronic and electrical systems under harsh conditions. Herein, we report a novel polyimide/magnesium oxide (PI/MgO) nanodielectric that exhibits high energy storage density (Ue) and charge–discharge efficiency (η) along with excellent cycling stability at elevated temperatures. Benefiting from the large bandgap of MgO and the extended interchain spacing of PI, the composite films can simultaneously achieve high dielectric constant and high breakdown strength, leading to enhanced energy storage density. The nanocomposite film doped with 0.1 vol% MgO can achieve a maximum Ue of 2.6 J cm−3 and a η of 89% at 450 MV m−1 and 150 °C, which is three times that of the PI film under the same conditions. In addition, embedding ultralow content of inorganic fillers can avoid aggregation and facilitate its large-scale production. This work may provide a new paradigm for exploring polymer nanocomposites with excellent energy storage performance at high temperatures and under a high electric field. Full article
