We have modified the Fiber by nano coating. it is difficult to make powder the fiber . Is there any method to characterize the fiber
As my previous experience, there was modified fiber of polyurethane filled with Polyaniline. In order to gain fuctional group, the fiber was characterized by using FTIR. Moreover, to investigate thermal stability and leads to determine the cristalization of polymers, we have done with DSC. Other suggestion might be you can try to find the different thickness of fiber when we prepared the fiber with different applied voltage by using SEM. Cheers.
Yes, UV-Vis spectra can be taken of solid materials (e.g. polyester fabric) as long as you have an instrument with an appropriate sample holder. However, if the material is too thick or dense for light to pass through it, you will need to obtain the spectra in reflectance mode, and not transmission mode like you would for a solution .
Its same here, XRD is a non destructive test where with right sample holder you can measure your sample in fiber/fabric form.
The special holders dedicated to solid samples comes with the instruments for specific models,: So, If they asked you to provide powders, then, maybe they do not have that kind of holder. So, Either you can ask them if they have such holders or source different place for your analysis.
If you modify with nanoparticles, they can be in the fiber. This leads to thinning and an increase in fiber thickness. This may be due to a violation of the technology of polyester. For this you need a microscope( optical or electronic).
