Dataset of publication "On the use of black tea waste as a functional filler for manufacturing self-stabilizing polyethylene composites: In-depth thermal analysis"

This dataset contains source data obtained during research under the project financed by National Science Centre Poland - NCN; UMO-2021/43/D/ST8/01491 "Research on the influence of the polymer composites processing conditions on the stabilizing effect of functional plant-derived fillers", relating to research results described in the publication "On the use of black tea waste as a functional filler for manufacturing self-stabilizing polyethylene composites: In-depth thermal analysis", DOI: 10.1016/j.indcrop.2024.120181 As part of the research work carried out, measurements were carried out using the following methods:- Antioxidant activity DPPH method | abbreviation: DPPH- Total phenolic content Folin-Ciocalteu method | abbreviation: TPC- Total flavonoid content| abbreviation: TFC- CIE Lab color analysis | abbreviation: COLOR- differential scanning calorimetry DSC | abbreviation: DSC- oxygen induction time raw data from DSC | abbreviation: DSC_OIT- TGA thermogravimetry | abbreviation: TGA- Antioxidant activity of composite materials| abbreviation: DPPH_composite- Fourier transform infrared spectroscopy | abbreviation: FTIR_spectra- Carbonyl Index (CI) values determined on the basis of FTIR | abbreviation: FTIR_CI As part of the work, the nomenclature corresponding to the content of black tea waste (BTW) in the polymer was used. The database designation refers to the concentration (1%, 2%, 5%, 10%), and in that case, it is abbreviated as the content of filler, letter C, and filler type (e.g., 5CBTW). Polymer not modified with filler is marked as LDPE SEB 853. The measurements of TGA thermogravimetry were carried out in an atmosphere of nitrogen (marked N2) at various heating rates of 2.5, 5, 10, 20 and 30 oC/min (the markings include the heating rate, e.g., 2.5 oC) and in an atmosphere of air (marked air) at heating rate 10 oC/min. In the case of files containing model fits, the designation "ozawa-flynn-wall", "model based" and "E", "A", "master plot" was introduced into the file name, respectively. File markings consist of:measurement type_material name_sample repetition number
