An interesting property of alkoxysilanes is their ability to be thermally decomposed (calcinated) to SiO2. Thermogravimetric analysis on polymerized TPM shows that above 700 °C, the organic matter in the silsesquioxane network burns off leaving a denser silica network. As a result, polymerized TPM particles shrink to about 17% of their original volume. The effect of the thermal treatment is evident by comparing SEM of samples before and after the heat treatment (Supplementary Fig. 10 ). Thermogravimetric analysis was performed with a PerkinElmer Pyris 1 TGA thermogravimetric analyser.

The Pyris 1 TGA is a thermogravimetric analyser (TGA) manufactured by PerkinElmer. It is designed to measure the change in the weight of a sample as a function of temperature or time in a controlled atmosphere. The Pyris 1 TGA provides accurate, high-resolution data on the thermal stability and composition of materials.

The thermal properties of polymeric coating were analysed using Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). DSC analysis was carried out using a Jade differential scanning calorimeter (Perkin Elmer, US). The temperature scale of the DSC instrument was calibrated using indium as a standard; which has a known melting point of 156.6°C. Sealed pans containing 2-4mg of sample were heated under a flow of nitrogen gas at a rate of 20°C/min from 20 to 300°C. TGA analysis was carried out using Pyris 1 TGA thermogravimetric analyser (Perkin Elmer, US). Under the flow of nitrogen gas and air, sealed pans containing 8-10mg of sample were heated at a rate of 20°C/min from 20 to 700°C.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
