Thermogravimetric analysis (TGA) of the raw material and hydrogels. Data underlying the research project "Gelatin-alginate hydrogels for hard-to-heal wounds" (GAlHyd)

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". 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. 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. 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.

本数据集收录了针对天然聚合物基水凝胶（明胶、海藻酸钠）开展研究过程中采集的数据，相关研究隶属于“用于难治性创面的明胶-海藻酸钠水凝胶”科研项目。本系列实验的核心目标为：通过监测样品以恒定速率升温过程中的重量变化，测定材料的热稳定性与挥发性组分占比。所有测试均在梅特勒托利多（METTLER TOLEDO）TGA2型热重分析仪上完成，热重分析数据处理采用STARe软件。薄膜/水凝胶样品的重量损失测试在氮气氛围（N₂，流速50 mL/min）下进行，样品初始质量约为10 mg。热重分析（Thermogravimetric Analysis, TGA）样品以10 ℃/min的升温速率从25 ℃逐步升温至500 ℃。热重分析可检测材料发生重量损失或无重量损失的临界温度，并可生成重量变化速率随时间或温度的变化关系。导数热重分析（Derivative Thermogravimetry, DTG）的目的在于确定材料重量损失速率最快的温度点。
