“…Tannic acid (TA), as an all-natural organic compound, possesses excellent antioxidant properties. − More importantly, thanks to its unique chemical structure, TA can form molecular self-assembled membranes with a variety of metal ions by complexation, − thus achieving surface functionalization. Herein, based on our previous work on surface functionalization, − we first activated the carbon fiber (CF) powders surface through biomimetic poly(catechol/polyamines) (PCPA), followed by the surface metallization via electroless silver-plating to obtain a highly conductive silver-plated CF (Ag/pCF) filler.…”

Conductive fillers are critical raw materials for many applications. However, vulnerability to salt spray corrosion remains the biggest problem for silver-plated conductive fillers. Herein, highly conductive silver-plated carbon fiber powders (Ag/pCF) were prepared via catechol/polyamine activation and subsequently formed a tannic acid/metal ion (TA@Me) complex inhibition layer. The electromagnetic interference (EMI) shielding effectiveness of the composite fabricated with original Ag/pCF decreased from 106.4 to 90.4 dB after a 4-cycle salt spray corrosion test, while the composites protected by TA@Me remained unchanged above 110 dB. Further research revealed that TA@Me could effectively block the penetration of Cl − , which is the primary corrosive chemical in a salt fog environment. Considering the high conductivity and the excellent antisalt spray performance, the Ag/pCF protected by the efficient TA@Me inhibition layer via an eco-friendly approach will be a priority alternative for high-performance EMIshielding applications.

In the present investigation, natural bone-derived hydroxyapatite (HA, 2 wt %) and/or exfoliated graphene (Gr, 0.1 wt %)-embedded polydimethylsiloxane (PDMS) elastomeric films were prepared using a vascular method. The morphology, mechanical properties, crystallinity, and chemical structure of the composite films were evaluated. The in vitro biodegradation kinetics of the films indicates their adequate physiological stability. Most of the results favored PDMS/HA/Gr as a best composite scaffold having more than 703% elongation. A simulation study of the microfluidic vascular channel of the PDMS/HA/Gr scaffold suggests that the pressure drop at the outlet became greater (from 1.19 to 0.067 Pa) unlike velocity output (from 0.071 to 0.089 m/s), suggesting a turbulence-free laminar flow. Our bioactive scaffold material, PDMS/HA/Gr, showed highest cytotoxicity toward the lung cancer and breast cancer cells through Runx3 proteinmediated cytotoxic T lymphocyte (CTL) generation. Our data and predicted mechanism also suggested that the PDMS/HA/Grsupported peripheral blood mononuclear cells (PBMCs) not only increased the generation of CTL but also upregulated the expression of RUNX3. Since the PDMS/HA/Gr scaffold-supported Runx3 induced CTL generation caused maximum cell cytotoxicity of breast cancer (MCF-7) and lung cancer (A549) cells, PDMS/HA/Gr can be treated as an excellent potential candidate for CTL-mediated cancer therapy.
