Thermogravimetric Analysis (TGA) - Thermal Characterization of Polymers

Thermogravimetric analysis (TGA) is a frequently used technique in thermal analysis. Its main use is to characterize materials by measuring change in their mass as a function of temperature or time. The TGA measurements are used mainly to determine the materials composition, thermal stabilities, oxidative stabilities, product lifetimes, decomposition rate, filler content, moisture and volatiles content, and effects of reactive atmospheres on materials.

Can you pls make a video about the quantity and concentration of fumes released for PVF at variable temperature

[@shahzadahmed5012]

Once again a very nice video. Could you please explain the difference between blend and composite?

[@PolymerWorld]

Please watch our video common polymer terms that explains difference between blend and composite.

[@maiphuong8158]

Do you have a video teaching to calculate the grafting efficiency of a polymer on nanoparticles by TGA ?

[@PolymerWorld]

Hi, we do not have a video but you can measure the graft density by following steps. (A) Generate TGA plot of pure polymer to find the degradation temperature. (B) At similar experimental condition, test the grafted nanoparticle. (C) If polymer is grafted on the nanoparticle, so weight loss at polymer degradation temperature indicate fractional graft density. (D) make sure to thoroughly wash grafted sample before the test.

[@ajitsatwadhar4249]

Please make a videos on numericals of polymer science and engineering for gate exam

Sure!

how to perform tga analysis for solid material like polymer reinforced composite......whether we kept as in solid cube or we should make powder of that solid. whether in both form it will give correct result

[@PolymerWorld]

To perform TGA of a composite, you can take 8-10mg of small pieces of extruded strand or lump. Simply cut or break the material into small pieces.

I am plastic engineer and i interest in lab activities please share most primary testing method.

[@PolymerWorld]

For characterization of polymer/plastic commonly used techniques are Thermal: DSC, TGA, DMA and TMA Mechanical: tensile/flexural tester, impact tester (Izod/Charpy) Morphology: light microscopy, electron microscopy (SEM, TEM) Electrical: two/four probe electrical conductivity test Rheology: parallel plate rheometer, capillary rheometer, cone and plate rheometer, and melt flow index

[@user-cs8bi7fy6z]

Can you please mention reference book/ material?

[@PolymerWorld]

This presentation is compilation of different research articles. But you can consult book Thermal analysis of polymers: fundamentals and applications by Joseph D Menczel. This book can be helpful.
