Another very vague question. First approach: I would assume that the melting point of your zeolite is higher than the boiling point of the polymer. Hence, one can heat the composite, evaporate the polymer and weigh the remaining material. Take into account that zeolites contain crystal water which will also disappear during burn-out, so you should heat a pure zeolite sample to determine the water fraction and hence the correction factor.
Dear Umma Habiba,
Whether you want to calculate the wt percent of filler material or to know the wt% of already synthesized polymeric composite ? Please clear your query firstly ?
I would also suggest TGA analysis, you can even use 5 or 6 mg of product. If you have the polymer by itself do TGA also to this sample it will be helpful for your data analysis later (remember to use for each analysis more or less the same quantity of initial material).
Thank you very much for your answers.actually, I add 1 wt % of zeolite to in chitosan and PVA blended solution and do electrospinning.i want to know the weight percentage of zeolite in the resulting electrospun composite fiber .so to do TGA I would need lots of fiber.
i can try with TGA.would you plz clear me the calculation from the curve
I would assume it would remain the same, 1wt%. Just to cross check, TGA is the best way to go forward, assuming there is at-least 30-50 C difference in the degradation temperature, and all the materials a thermally inert i.t they don't react with each other.
