Special Issue Information

Dear Colleagues,

There has been growing interest in recent years in functional materials across various disciplines such as water and wastewater treatment, renewable energy research, catalytic processes, and pollution controls. Functionalized materials can be used to enhance the functionalities of the materials in increasing the water fluxes in membrane filtration, enhancing the transports of protons in proton-exchange membrane for fuel cell applications, increasing the yields of products in catalytic reactions, minimizing the discharges of harmful contaminants to the environment, etc. The high demand in functional materials has led to the development of functionalized materials through sustainable chemistries, which is beneficial from economic and environmental perspectives.

This Special Issue aims to address the development and application of functional materials with promising performance using sustainable raw materials with wide availability. Moreover, the integration of green synthesis routes and their progresses in producing the functional materials for various applications are greatly welcomed.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Functionalized polymers and their composites;
  • Functionalized nanoparticles and their composites;
  • Functionalized quantum dots and their composites;
  • Production and application of functionalized materials in various fields;
  • Green approaches in synthesizing functional materials.

We look forward to receiving your contributions.

Verapamil hydrochloride, a calcium channel-blocking agent, is detectable in receiving water bodies and affects the well-being of aquatic organisms. Membrane filtration could be effective in removing such pharmaceutical contaminants. However, limited studies have employed commercial membranes, such as polyvinylidene fluoride (PVDF), in removing verapamil from water sources, owing to their low solution fluxes, poor antibacterial properties, and high surface hydrophobicity. Efforts are needed to create the PVDF membrane suitable for removing verapamil from water sources. In this study, PVDF composite membranes incorporated with from 0 to 0.10 wt% silver-doped graphene oxide quantum dots (Ag−GOQD) were evaluated in terms of their morphological structures, elemental composition, surface roughness, hydrophilicity, verapamil rejection capability, anti-fouling, and antibacterial capabilities. The pure PVDF membrane showed the lowest verapamil rejection (73.66 ± 2.45%), highest surface roughness (mean surface roughness, Sa = 123.80 nm), and least hydrophilic membrane surface (contact angle = 79.06 ± 4.53°) when compared to other membranes incorporated with nanocomposites. However, the membrane incorporated with 0.10 wt% Ag−GOQD showed the smoothest and the most hydrophilic membrane surface (Sa = 13.10 nm and contact angle = 53.60 ± 4.75°, respectively), associated with the highest verapamil rejection (96.04 ± 1.82%). A clear inhibition zone was spotted in the agar plate containing the membrane incorporated with Ag−GOQD, showing the antibacterial capability of the membrane. The overall improvement in morphological structures, surface smoothness, surface hydrophilicities, permeabilities, verapamil rejection abilities, and anti-fouling and antibacterial capabilities indicated a great potential to incorporate Ag−GOQD in PVDF membrane fabrication.
