Catechol Moiety

The unusual amino acid 3,4-dihydroxyphenylalanine with a catechol side chain is believed to impart both adhesive and cohesive characteristics of mussel adhesive proteins. Inspired by the pH-tunable coordination between catechol moiety and Fe3+, responsible for the high extensibility and self-healing properties of the cuticle of mussel byssal threads, we report the synthesis of a dopamine modified Pluronic F68 block copolymer (PluF68-Dopa) with high coupling efficiency and utilization of catechol-Fe3+interactions to yield cross-linking hydrogels with enhanced mechanical strength and self-healing properties. Ultraviolet-visible spectroscopy was used to identify PluF68-Dopa-Fe3+complex species via pH control in dilution solution. At lower pH, concentrated PluF68-Dopa-Fe3+mixture remained a fluid, whereas at higher pH an elastomeric gel immediately formed. PluF68-Dopa-Fe3+cross-linked hydrogels are not only pH-responsive but also possess self-healing properties due to the reversible bond interactions between catechol moiety and Fe3+. These new biomimetic materials are expected to have potential biomedical and engineering applications.

A technology for the formation of electrically conductive nanostructures from single-walled carbon nanotubes (SWCNT), multi-walled carbon nanotubes (MWCNT), and their hybrids with reduced graphene oxide (rGO) on Si substrate has been developed. Under the action of single pulses of laser irradiation, nanowelding of SWCNT and MWCNT nanotubes with graphene sheets was obtained. Dependences of electromagnetic wave absorption by films of short and long nanotubes with subnanometer and nanometer diameters on wavelength are calculated. It was determined from dependences that absorption maxima of various types of nanotubes are in the wavelength region of about 266 nm. It was found that contact between nanotube and graphene was formed in time up to 400 fs. Formation of networks of SWCNT/MWCNT and their hybrids with rGO at threshold energy densities of 0.3/0.5 J/cm2 is shown. With an increase in energy density above the threshold value, formation of amorphous carbon nanoinclusions on the surface of nanotubes was demonstrated. For all films, except the MWCNT film, an increase in defectiveness after laser irradiation was obtained, which is associated with appearance of C–C bonds with neighboring nanotubes or graphene sheets. CNTs played the role of bridges connecting graphene sheets. Laser-synthesized hybrid nanostructures demonstrated the highest hardness compared to pure nanotubes. Maximum hardness (52.7 GPa) was obtained for MWCNT/rGO topology. Regularity of an increase in electrical conductivity of nanostructures after laser irradiation has been established for films made of all nanomaterials. Hybrid structures of nanotubes and graphene sheets have the highest electrical conductivity compared to networks of pure nanotubes. Maximum electrical conductivity was obtained for MWCNT/rGO hybrid structure (~22.6 kS/m). Networks of nanotubes and CNT/rGO hybrids can be used to form strong electrically conductive interconnections in nanoelectronics, as well as to create components for flexible electronics and bioelectronics, including intelligent wearable devices (IWDs).
