Special Issue Information

Dear Colleagues,

Coatings systems, as one of the most effective surface modification strategies, are attracting more and more research attention. Unlike other surface modification approaches, coatings treatment technology could realize the goal of multi-functionalizing matrix materials. For instance, various coatings systems endow matrix materials with superior anti-corrosive, anti-friction, anti-oxidation, anti-bacterial, biocompatible, and electromagnetic shielding properties. With different manufacturing methods, the obtained coatings are characterized via specific testing methods based on the proposed potential application of the coatings. Among all these types of coatings, the bio-coatings are the coatings with favourable biocompatibility or bioactivity, and their targeted application is in the biomedical field.

This Special Issue will serve as a forum for papers covering the following themes:

  • Exploration of optimal bio-coatings’ fabrication techniques.
  • Organic, inorganic, or composite bio-coatings manufactured by chemical or physical vapour deposition, laser cladding, plasma deposition, thermal spraying, anodization, sol-gel method, 3D printing, etc.
  • Novel characterization methods applied to assess the bio-coating system.
  • Property measurement and evaluation of the bio-coatings in the proposed application.
  • Reliability or failure behaviour and their failure mechanism of bio-coatings under specific service environment.
  • Machine learning predicting and verifying the relationship between the fabrication process and bio-coatings’ properties.
  • Biological characterization on the coating system.
  • Evaluation of biocompatibility, bioactivity, and biotribological properties of the coating.
  • Assessment of the antibacterial coatings.

In recent years, the synthesis of nanofibers using plant extracts and bioactive materials has been extensively studied and recognized as a suitable and efficient method applicable in the food packaging field. In this research, an antimicrobial material was introduced by the immobilization of glucose oxidase (GOx) in Nylon–Ag masterbatch/chitosan/Rosmarinus officinalis extract nanofiber via electrospinning technology. Nylon–Ag masterbatch/chitosan/Rosmarinus officinalis composite nanofibrous membranes with an average diameter of 207 ± 18 nm were successfully prepared using the electrospinning technique. The chemical properties of membranes were analyzed by Fourier transform infrared spectroscopy (FTIR) and the morphological characterization of nanofibers was evaluated with field emission scanning electron microscopy (FE-SEM). Moreover, enzymatic activity of GOx was determined by the Carmine method. FTIR results showed the successful incorporation of glucose oxidase and Rosmarinus officinalis into the nanofiber composite. Immobilized GOx showed high (79.5%) enzymatic activity in the optimum sample. The Rosmarinus officinalis, glucose oxidase-incorporated Nylon–Ag masterbatch/chitosan nanofibrous exhibited excellent antimicrobial activity on both gram-negative bacterium Escherichia coli (97.5%) and gram-positive bacterium Staphylococcus aureus (99.5%). The antibacterial and antioxidant Nylon–Ag masterbatch/chitosan/Rosmarinus officinalis/GOx nanofibrous membrane showed higher potential, compared to the control sample, to be used as food packaging by improving the shelf life and maintaining the quality of food stuffs. Therefore, this research recommends it as a promising candidate for food preservation applications. Full article

There is a growing interest in enhancing the bioactivity of TC4-based metallic biomaterials, which are known for their excellent biocompatibility. Bioactive glass (BG) has been recognized for its high potential in promoting bioactivity, particularly in osteo tissue engineering. This study focuses on investigating the influence of BG addition on the microstructure and electrochemical properties of TC4 coatings. The TC4/BG composite coatings were fabricated through laser cladding, and their microstructure was characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The electrochemical properties of the coatings were assessed through electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization tests in three different solutions. The results revealed that the incorporation of BG had a significant impact on the microstructure of the TC4 coatings, leading to the formation of a well-defined interface between the TC4 matrix and the BG aggregates. The distribution of BG aggregates within the TC4 matrix coating was found to be random and unrelated to the specific regions of the coating. The metallographic microstructure variations were attributed to different heat dissipation conditions during the laser cladding process. Furthermore, the electrochemical corrosion behavior of TC4/BG composite coatings reveals that they exhibit stability similar to that of passive films and good resistance against media corrosion compared to TC4, while also showing enhanced corrosion resistance in 3.5 wt% NaCl and Dulbecco’s modified Eagle medium (DMEM) solutions, indicating their potential for biomedical applications; however, the corrosion resistance decreases gradually in all solutions, potentially due to the elevated Cl− concentration. Further research can explore bioactivity enhancement of TC4/BG composite coatings and investigate the long-term stability and biological response of these coatings in diverse physiological environments.
