Linear rheology measurements: dynamic strain sweep and dynamic frequency sweep of two commercial samples of poly(lactic acid)

This data set includes the measurements of the Dynamic Strain Sweep (DSS) and Dynamic Frequency Sweep (DFS) performed during Petra Bacova's stay at IESL-FORTH in Heraklion, Greece in summer 2024. 

The measured materials are two commercial samples of poly(lactic acid) (PLA): recycled PLA and PLA3D850. The technical sheets downloaded from the producer [1] are included in the directory.

The data are saved in two formats, txt and RSD0X format used in rheometers of TA Instruments. The measurements were performed with ARES rheometer. 

DSS files are labeled as follows: method_Ttemperatureingrades.

DFS files are labelled as follows: method_referencegap_Ttemperatureingrades_maximumstrain

The description of each method, the sample preparation as well as the setting of the reference gap and other parameters is described in the technical note elsewhere. [2]

Data were not corrected for rheometer compliance. 

The temperature ramp tests of these samples are publicly available [3]
