This project focuses on the development of nanodiamond-reinforced electrospun nanofibers with enhanced mechanical, thermal, and functional properties. By integrating nanodiamonds into polymer nanofiber matrices through advanced electrospinning techniques, we engineer high-performance nanocomposite materials tailored for a wide range of applications. Current research explores their potential in energy devices, environmental technologies, sensing systems, filtration, and advanced functional materials. Through the synergy between nanodiamond nanomaterials and electrospun architectures, we aim to create next-generation nanofibrous platforms with superior performance and multifunctionality.
Nanodiamond-modified Electrospun PVDF Nanofibers
This study investigates the enhancement of piezoelectric performance through the incorporation of nanodiamonds (NDs) into poly(vinylidene fluoride) (PVDF) nanofibers at varying concentrations. The addition of NDs notably promotes the formation of the electroactive β-phase in PVDF, achieving maximum βγ-phases contents of 88.02 % (FTIR) and β-phase content of 84.53 % (XRD) at 1 wt% NDs loading. This increase in β-phase content correlates strongly with improved piezoelectric output...

Hybrid Electrospun–Electrosprayed PVDF–Nanodiamond composites
This study developed polyvinylidene fluoride (PVDF) nanofibers reinforced with nanodiamond (ND) using a dual electrospinning–electrospraying method, allowing simultaneous fiber formation and filler deposition at ND loadings from (0 to 10 wt%). High-resolution SEM images confirmed uniform, bead-free fibers with evenly distributed NDs, indicating effective processing and strong filler incorporation. Structural analyses by XRD and FTIR showed that ND addition maintained PVDF’s α and β crystalline phases. TGA revealed notable thermal improvements, suggesting enhanced interfacial stability. Piezoelectric measurements demonstrated superior performance for the PVDF/ND approximately double that of pure PVDF. These results highlight that the integrated fabrication strategy effectively enhances thermal, mechanical, and piezoelectric properties, establishing PVDF/ND nanocomposites as strong candidates for energy-harvesting applications.
