Article Abstract
A novel nanoreinforced adhesive film has been developed to detect adhesive deformation and crack propagation along the bonding line by means of the electrical response of the material. Adhesive films were doped by spraying an aqueous dispersion of carbon nanotubes (CNTs) over the surface. To determine the sensitivity of bonded joints, single lap shear (SLS) and mode-I fracture energy tests have been carried out while their electrical response has been measured. It has been found that CNT-doped adhesive films are able to detect adhesive deformation and final failure for SLS specimens and crack initiation and propagation along the bonding line for mode-I specimens with a high sensitivity. Sudden increases on electrical resistance are correlated to a rapid growing of the crack length due to instability on crack propagation in a tick-slip case, whereas specimens with a more uniform crack propagation are linked to a steadier increase on electrical resistance, and both of them are properly correlated to the mechanical response. By analyzing more in detail the electrical response and comparing with theoretical approaches, the stick-slip behavior is associated with the presence of porosity and lack of adhesives because of possible manufacturing issues such as adhesive overflowing. These statements are also validated by microstructural analysis. Therefore, the potential and applicability of the proposed adhesive films for evaluating the structural integrity has been demonstrated.

Polyphenols, rich in phenolic structures, are widely found in plants and known for disturbing the cellular oxidative stress and regulating the signal pathways of tumor proliferation and metastasis, making them valuable in cancer therapy. Polyphenols display high adherence due to the presence of phenolic hydroxyl groups, which enables the formation of covalent and non-covalent interactions with different materials. However, nonspecific adhesion of polyphenols carries significant risks in applications as polyphenols might adhere to proteins and polysaccharides in the bloodstream or gastrointestinal tract, leading to thrombosis and lithiasis.

Adhesives are important in creating multilayer products, such as in packaging and construction. Most current hot-melt adhesives such as poly(ethylene-co-vinyl acetate) (EVA) and polyurethanes lack chemical recyclability and do not easily de-bond, complicating recycling. Here, we achieved tunable adhesive properties of chemically recyclable polyolefin-like multiblock copolymers through regulating the incorporation of crystalline hard blocks, amorphous soft blocks, and ester content highlighted by adhesive strengths up to 6.

The development of high-performance neural interfaces is critical for advancing brain-machine communication and treating neurological disorders. A major challenge in neural electrode design is achieving a seamless biological-electronic interface with optimized electrochemical properties, mechanical stability, and biocompatibility. In this study, we introduce a hierarchical micronanostructured poly(3,4-ethylenedioxythiophene)-polydopamine (PEDOT-PDA) coating on titanium nitride (TiN) microelectrodes engineered to enhance electrophysiological signal recording and neural integration.

Chitosan and tannin are both promising renewable materials for food packaging; however, their effectiveness is limited by incomplete interactions between them. Therefore, phytic acid and octadecylamine were employed to create chitosan-tannin-phytic acid-octadecylamine (CTPO) films that are flame-retardant, UV-resistant, antibacterial and hydrophobic for food packaging applications. The findings indicate that the CTPO film exhibited excellent hydrophobicity and mechanical properties, with a water contact angle of 133.
