Piezoelectric Polymers and Superhydrophobic Membranes for Energy and Water
This research community develops advanced functional materials, primarily polyvinylidene fluoride (PVDF) composites and engineered membranes, to solve two distinct engineering problems: converting mechanical motion into electricity and separating fluids such as oil from water.
The work centers on two material systems. The first involves flexible piezoelectric and triboelectric nanogenerators, often using PVDF, graphene oxide, or barium titanate composites, designed to harvest energy from motion for sensors and wearable devices. The second focuses on superhydrophobic and oleophilic membranes, frequently incorporating PVDF or hollow fiber structures, for oil-water separation, desalination, and wastewater treatment. Recurring methods include electrospinning, composite film fabrication, and surface modification to enhance hydrophobicity or dielectric properties. Applications range from self-powered sensors and energy storage to industrial water purification and anti-icing coatings.
The community is most heavily represented in research tracked for Fluorine, accounting for 14.6% of all Fluorine research, with 12,485 papers. It also holds significant shares in Barium (3.5%) and Titanium (3.0%) research.
The community comprises 39,986 papers, published predominantly in the Journal of Membrane Science, Separation and Purification Technology, and ACS Applied Materials & Interfaces.
Recent work continues to focus on refining superhydrophobic coatings for anti-icing applications, developing flexible triboelectric nanogenerators for wearable sensing, and improving interfacial solar evaporation and reverse osmosis membranes for water treatment.
