Special Issue Information

Dear Colleagues,

Graphene has been designated a “miracle material” owing to its combination of unprecedented properties, such as high intrinsic mechanical strength, high electrical and optical features, high thermal conductivity, and exceptionally high surface area. More recently, graphene-based multifunctional polymer composites have presented new opportunities in a wide range of applications, such as catalysis, supercapacitors, membranes, energy storage, optoelectronic devices, aerospace, and biomedicine. These advanced graphene-based multifunctional composites could constitute a fundamental and versatile building block of future technologies as we enter the post-carbon era.

In this context, it gives us great pleasure to edit the second edition of this Special Issue on “Advanced Graphene-Based Polymer Composites II”. This Special Issue will cover basic scientific and engineering aspects such as novel manufacturing approaches for graphene-based composites and their structural manipulation for a diverse range of applications, involving, but not limited to, pharmaceutical nanotechnology, tissue engineering, energy storage, water treatment, catalysis, and optoelectronics.

We would like to invite you to submit a manuscript to this Special Issue. Short communications, full papers, and reviews related to graphene-based composites are all welcome.

Globally, researchers have devoted consistent efforts to producing excellent coating properties since coating plays an essential role in enhancing electrochemical performance and surface quality. In this study, TiO2 nanoparticles in varying concentrations of 0.5, 1, 2, and 3 wt.% were added into the acrylic-epoxy polymeric matrix with 90:10 wt.% (90A:10E) ratio incorporated with 1 wt.% graphene, to fabricate graphene/TiO2 -based nanocomposite coating systems. Furthermore, the properties of the graphene/TiO2 composites were investigated by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), ultraviolet-visible (UV-Vis) spectroscopy, water contact angle (WCA) measurements, and cross-hatch test (CHT), respectively. Moreover, the field emission scanning electron microscope (FESEM) and the electrochemical impedance spectroscopy (EIS) tests were conducted to investigate the dispersibility and anticorrosion mechanism of the coatings. The EIS was observed by determining the breakpoint frequencies over a period of 90 days. The results revealed that the TiO2 nanoparticles were successfully decorated on the graphene surface by chemical bonds, which resulted in the graphene/TiO2 nanocomposite coatings exhibiting better dispersibility within the polymeric matrix. The WCA of the graphene/TiO2 coating increased along with the ratio of TiO2 to graphene, achieving the highest CA of 120.85° for 3 wt.% of TiO2. Excellent dispersion and uniform distribution of the TiO2 nanoparticles within the polymer matrix were shown up to 2 wt.% of TiO2 inclusion. Among the coating systems, throughout the immersion time, the graphene/TiO2 (1:1) coating system exhibited the best dispersibility and high impedance modulus values (Z0.01 Hz), exceeding 1010 Ω cm2.
