Incorporation of nitrogen-doped carbon dots synthesized from pomelo peels into PVA as highly antioxidant and UV-blocking food packaging film

This dataset supports a study on the synthesis and application of nitrogen-doped carbon dots (N-doped CDs) derived from the albedo of pomelo peel waste via hydrothermal treatment at 200 °C for 12 hours. Urea was added as a nitrogen source in varying amounts (0–2.0 g) to modify the surface chemistry of CDs, influencing their optical, antioxidant, and UV-blocking properties. The dataset includes raw and processed data on particle size (TEM and DLS), UV–vis absorption, fluorescence emission spectra, zeta potential, quantum yield measurements, UV-blocking measurement, and antioxidant activity (DPPH assay). Mechanical, thermal, and barrier properties of poly(vinyl alcohol) (PVA) films incorporating different CD loadings are also provided. These data were used to evaluate the multifunctional performance of the CDs-loaded PVA films as active packaging materials. The dataset enables reproducibility and facilitates further analysis of biomass-derived carbon dots for food packaging applications.

## Description of the Data and File Structure

This dataset provides the raw and processed data necessary to replicate the analyses of:

1. The effect of the amount of urea added in the synthesis on the properties of the resulting carbon dots (CDs).
2. The effect of the type and amount of the incorporated CDs on the properties of the poly(vinyl alcohol) (PVA) films.

The dataset is organized in two Excel files:

* `Datasets_for_CDs_characterization.xlsx`
* `Datasets_for_film_characterization.xlsx`

## Files and Variables

### 1. `Datasets_for_CDs_characterization.xlsx`

**Description:** Contains raw and processed data for the characterization of CDs. Samples are labeled according to the amount of urea (0.0–2.0 g) used during synthesis. For example, `CDs-0g`, `CDs-0.5g`, `CDs-1.0g`, and `CDs-2.0g` corresp...,
