***General Introduction***
This dataset contains data collected during investigation of hydrogels based on natural polymers (gelatin, sodium alginate),
as part of the research project "Gelatin-alginate hydrogels for hard-to-heal wounds"(April-November 2023)
It is being made public both to act as supplementary data for publications and the PhD
thesis of Olha Maikovych and in order for other researchers to use this data in their own work.
The data in this data set was collected in the Institut des Molecules et Materiaux du Mans of the
Le Mans University - Faculty of Science and Technology, between 1 April 2023 and 30 November 2023.
This research project was made possible by a MSCA4Ukraine grant, ID number 1232572.
Funded under the EU’s Marie Sklodowska-Curie Actions. 

***Purpose of the test campaign***
The purpose of these experiments was to determine a material's thermal stability and its fraction of volatile
components by monitoring the weight change that occurs as a sample is heated at a constant rate.

***Test equipment***
All tests were performed on a TGA2 METTLER TOLEDO instrument. The STARe software was using for TGA treatment.
The weight loss of the film/hydrogel sample was measured in a nitrogen atmosphere (N2, 50 ml/min) with an initial mass of about 10 mg. 
Thermogravimetric analysis samples were gradually heated from 25 °C to 500 °C at a heating rate of 10 °C per minute. 
 
***Description of the data in this data set***
The data included in this data set has been organised per specimen. The files (.pdf) follow the
nomenclature system: X_Type of hydrogel_(Ratio)_Method of drying with
X = indicating the number of synthesis
Type of hydrogel = "G" - based on gelatin, "GA" - based on gelatin-alginate
Ratio = ratio of cross-linker and base
Method of drying = indicating that the sample was air dried , unless otherwise specified, then the original sample was taken
The files (.txt) follow the same nomenclature system and also plus indication on the type of analysis. 
The files (.txt) have numerical information about tga/dtg measurements.
TGA detects the temperature at which a material loses weight or does not lose weight. 
It creates the rate of change in weight as a function of time or temperature. 
The purpose of DTG analysis is to see the temperature at which the material loss is the most.
The file (.rar) have the information about measurements of the raw material.
