Data set on paper ''Circular poly(ethylene terephthalate) with lignin-based toughening additives''

This data set consisted of the original data set for the paper ''Circular poly(ethylene terephthalate) with lignin-based toughening additives''. It has two folders: lignin characterization and fiber characterization. The former lignin characterization includes 13C Nuclear Magnetic Resonance, 31P Nuclear Magnetic Resonance, Gel Permeation Chromatography combined with three detectors: multi-angle light scattering, intrinsic viscometer, and differential refractive index, thermal gravimetric analysis (TGA), and differential scanning calorimetry (DSC). The latter fiber characterization for LignoPET composite includes scanning electron microscopy (SEM) images, dynamic mechanical analysis (DMA), Instron tensile tests, differential scanning calorimetry (DSC), and optical microscopy.
