Synthesis of a reactive bio-based flame retardant (TVD) with P/N elements for epoxy resins TVD formed a cross-linked mesh structure with the epoxy resin network TVD improves the flame retardancy and smoke suppression of modified epoxy resins TVD improves the mechanical properties of epoxy resin.

A new composite material was developed using a “achieve two things at one stroke” strategy. This material demonstrated two noteworthy applications. Firstly, it exhibited a specific capacitance of up to 377 F/g. Even after 1000 charge/discharge cycles, the specific capacitance remained at 91.3% of its initial value. Secondly, it exhibited excellent photosensitivity properties, with sensitivity to ultraviolet light being 9.2 times that of red light. This conductive polymer shows promising potential in electrode materials and photosensitive devices.

Four types of oil shale semi-coke (OSSC) powders with varying particle sizes are obtained by controlling the ball milling time. LDPE composites are prepared using 2500-mesh heavy calcium powder as a contrast filler. The LDPE/OSSC-40-30 composites exhibit the best mechanical properties and interface interaction parameters among the tested composites.

Enhancement of long chain branched polypropylene microcellular foaming by self-assembled β nucleating agent.

A crystalline tetrapeptide Gly-Ala-Gly-Ala derived from the repetitive segments of the primary sequence of silk fibroin was grafted onto the waterborne polyurethane backbone. The tetrapeptides aggregated via additional hydrogen bonds to form crystalline domains, which served as physical crosslinking points to significantly improve the mechanical properties and biocompatibility of WPU.

This research describes a simultaneous process to obtain cellulose nanocrystals (CNC) and bioactive red onion extract (OPE) from red onion waste. Both biomaterials were used to enhance the properties of polyvinyl alcohol (PVA)-based films. The bio-nanocomposites were fully characterized, and their mechanical and antibacterial activities were investigated. The results highlight that the formulated PVA-CNC(5%)-OPE exhibits effective antibacterial properties, making it appropriate for antibacterial-activated food packaging products.

Biobased thermoplastic polyurethane/polylactic acid blend foams are fabricated by thermally induced phase separation method. The produced foams are loaded with natural extracts of Curcuma longa L. and Hypericum perforatum for WD application. The TPU/PLA foams loaded with C. longa L. and H. perforatum extracts show the best positive effect upon cells growth and development. Overall, all investigated foams, especially those loaded with extracts, are beneficial for WD and healing applications.

The rigid-flexible segments in the PI binders work synergistically during the electrochemical process, in which the rigid segments of aromatic units with strong lithiophilic CO group provided the necessary mechanical support and affinity with electrolytes, while the flexible segments endow the necessary solubility of PIs in NMP and provide the buffer effect to the volume change during the charge/discharge process.
