“…It can be also seen from the SEM images that the PDA-coated CNTs can aggregate more than bare CNTs. It was reported that there was an increase in the hydrophobicity of CNT after PDA coating, and the increased hydrophobicity and aggregation enabled the utilization of PDA-coated materials' new properties e.g., preventing corrosion and so on [43,52,53].…”

Carbon nanotubes (CNTs) due to their outstanding mechanical, thermal, chemical, and optical properties were utilized as a base material and were coated with polydopamine (PDA) (PDA@CNT) via the simple self-polymerization of dopamine (DA). Then, PDA@CNT coatings of up to five layers were examined for potential biomedical applications. The success of multiple coating of CNTs with PDA was confirmed via increased weight loss values with the increased number of PDA coatings of CNTs at 500 °C by thermogravimetric analysis. The surface area of bare CNTs was measured as 263.9 m2/g and decreased to 197.0 m2/g after a 5th coating with PDA. Furthermore, the antioxidant activities of CNT and PDA@CNTs were determined via total flavonoid content (TFC), total phenol content (TPC), and Fe(III)-reducing antioxidant power (FRAP) tests, revealing the increased antioxidant ability of PDA@CNTs with the increasing numbers of PDA coatings. Moreover, a higher inhibition percentage of the activity of the alpha-glucosidase enzyme with 95.1 ± 2.9% inhibition at 6 mg/mL PDA-1st@CNTs concentration was found. The CNT and PDA@CNTs exhibited blood compatibility, less than a 2.5% hemolysis ratio, and more than 85% blood clotting indexes. The minimum inhibition concentration (MIC) of PDA-5th@CNTs against E. coli and S. aureus bacteria was determined as 10 mg/mL.

Characterizing and understanding composite polymeric systems' rheological behavior is essential to tune their melt flow in polymer processing machinery. Also, rheological tests are suitable tools to evaluate the microstructure and interface adhesion of polymeric composites, which are relevant parameters on the composite performance in their applications. Poly(acrylonitrile‐co‐butadiene‐co‐styrene) (ABS) and its composites are essential materials used to manufacture consumer goods necessary to maintain the quality of life of human beings. In this work, we report on polymer systems based on ABS and poly(styrene‐block‐ethylene‐co‐butylene‐block‐styrene)‐graft‐maleic anhydride (SEBS‐g‐MA) as polymer matrix containing dispersed copper microparticles (ABS:SEBS‐g‐MA:Cu). Polydopamine, a bioinspired polymer, was applied as a filler‐matrix interface compatibilizer of the composites. The linear viscoelastic rheological measurements evidence a shear‐thinning behavior for the composites, and the polydopamine coating affects the polymer phase's relaxation time. The cohesive energy density (Ec) and SEM micrographs indicate good adhesion between copper and ABS:SEBS‐g‐MA due to polydopamine interfacial adherence.
