Petroleum-based plastics are indispensable in modern society, yet their non-degradable nature and toxic byproducts have led to severe environmental pollution and ecological threats. The development of bioplastics that combine high optical transparency, excellent tensile strength, and recyclability remains a significant challenge on the path toward sustainability. To address this challenge, a flexible, transparent bioplastic with exceptional mechanical performance, exhibiting a tensile strength of 77.61 MPa and a Young’s modulus of 2022.02 MPa, was prepared via a straightforward self-assembly strategy using gelatin, TEMPO-oxidized cellulose nanofibril and hyaluronic acid, and as raw materials, based on a supramolecular network formed through multiple hydrogen bonding. Based on this, a dense double conductive layer was fabricated on the bioplastic surface via spin-coating of silver nanowires (AgNWs) and subsequent magnetron sputtering of indium tin oxide (ITO), which imparted high electrical conductivity (455.4 S·m^-1), outstanding electromagnetic interference shielding (24.26 dB), and efficient electrothermal heating performance. More importantly, the ITO-assisted welding effect on the AgNWs networks enhanced electrical conductivity, interfacial adhesion, bending durability, and long-term environmental stability. With these integrated functionalities, the conductive bioplastic emerges as a sustainable enabler for next-generation flexible electronics and personal thermotherapy.

A three-dimensional copper metal-organic framework with the rare chabazite (CHA) topology namely FJI-Y11 has been constructed with flexibly carboxylic ligand 5,5'-[(1,4-phenylenebis(methylene))bis(oxy)]diisophthalic acid (H₄L). FJI-Y11 exhibits high water stability with the pH range from 2 to 12 at temperature as high as 373 K. Importantly, FJI-Y11 also shows high efficiency of hydrogen isotope separation using dynamic column breakthrough experiments under atmospheric pressure at 77 K. Attributed to its excellent structural stability, FJI-Y11 possesses good regenerated performance and maintains high separation efficiency after three cycles of breakthrough experiments.
