Summary: In this study, a stretchable, foldable, and flexible commercial sponge has been converted into a conducting material by incorporating polypyrrole (PPy). Bismuth oxide (Bi2O3) electrode material with a wool ball-like morphology is synthesized over PPy-coated sponge, creating a hybrid Bi2O3@PPy electrode. The unique morphology of Bi2O3 and the porous structure of PPy@sponge result in a high number of active sites and short diffusion pathways, enabling efficient electron-ion transportation. A pencil-type asymmetric supercapacitor using Bi2O3@PPy//graphite rod electrodes delivers high energy and power densities, as well as excellent cycling stability.

Summary: Organic active materials have great potential to replace inorganic counterparts due to their adjustable redox activity, mild synthesis conditions, and multi-electron reactions. However, their application is limited by issues such as dissolution in aqueous electrolyte and low electrical conductivity. In this study, self-assembled nanorods of perylene-3,4,9,10-tetracarboxylic dianhydride (NRPTCDA) were synthesized on carbon cloth for high-performance Zn-ion storage. By optimizing the synthesis conditions, the vertical orientation and length of the nanorods were controlled, facilitating Zn-ion insertion-deinsertion. The NRPTCDA cathode achieved a high capacity of 127.5 mAh g-1 at a current density of 1 A g-1 in an aqueous Zn-ion battery, with a retention of 82.10 mAh g-1 even at a high current rate of 50 A g-1. The structure-controlled NRPTCDA exhibited 90.1% rate capability at 100 mV s-1 and 78.91% capacity retention over 10,000 galvanostatic charge-discharge cycles at a current density of 10 A g-1. Ex situ X-ray diffraction, attenuated total reflectance-Fourier transform infrared spectroscopy, and field emission scanning electron microscopy measurements confirmed the structural, chemical, and morphological stability and reversibility of NRPTCDA electrodes for Zn2+ ion storage.

Summary: With the rapid growth in the manufacturing industry, the emission of hazardous volatile organic compounds (VOCs) has increased, leading to a demand for highly sensitive, selective, and stable gas sensors. We have addressed the issues associated with chemoresistive alcohol sensors by using iodine-doped polyvinyl acetate (IPVAc) films, which offer benefits like low power consumption, ease of manufacture, and long-term stability. These films demonstrated high selectivity for alcohols over other VOCs and stable sensitivity performance over a wide temperature range. Therefore, plasma-polymerized IPVAc films can be applied for highly selective, sensitive, and stable VOC sensing applications.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study focuses on the development of high-performance, low-migration photoinitiators. A polymerizable photoinitiator (VBP) was synthesized by introducing an ethylene group into benzophenone, and three different molecular weight single-component photoinitiators (PVBN1-3) were synthesized based on VBP. The results show that these new photoinitiators have stronger absorption ability compared to benzophenone and significantly reduce the migration of initiators and co-initiators, addressing the safety concerns caused by migration.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.

In this study, a series of isosorbide-2-aryl carboxylate-5-methacrylate monomers (ArIMAs) were synthesized by functionalizing isosorbide 5-methacrylate with various aromatic lignin-inspired esters. These monomers were polymerized to obtain high molecular-weight poly(aryl carboxylate isosorbide methacrylates) (PArIMAs). The resulting polymers showed high glass transition temperatures and thermal stability, making them suitable for use as high-performance plastics and coatings.
