Polyvinylidene fluoride foam Reference

The Zotek F30 Near-Infrared Reflectance Dataset provides spectral reflectance measurements of Zotek F30, a closed-cell polyvinylidene fluoride (PVDF) foam widely used in demanding engineering applications due to its lightweight structure, thermal stability, chemical resistance, and low moisture absorption. The dataset comprises 30 individual reflectance spectra, with each spectrum sampled over the 900–1700 nm wavelength range at regular wavelength intervals. Each record represents a single material sample, while individual columns correspond to discrete wavelength bands expressed in nanometres (nm). Reflectance values are provided as normalized decimal measurements suitable for quantitative spectral analysis. The dataset is organized in a comma-separated values (CSV) format with clearly defined sample identifiers and material labels, enabling straightforward integration into scientific workflows and analytical software. The consistent data structure facilitates comparison of spectral responses across multiple observations while preserving compatibility with commonly used data processing environments. This dataset supports research in materials science, spectroscopy, polymer characterization, aerospace materials, engineering materials, quality assessment, and non-destructive material evaluation. It may also serve as a reference resource for comparative spectral studies involving advanced polymeric and cellular materials. The dataset is accompanied by structured metadata describing the data organization, wavelength representation, and file format to promote reproducibility, interoperability, and long-term reuse within the scientific community.
