Polymer Analysis
Polymer Analysis
AMIA Laboratories specializes in the investigation and characterization of polymeric systems using the latest advances in x-ray diffraction. Orientation studies can be efficienty carried out using a two-dimensional detector specifically developed for the complex diffraction patterns generated by polymers. Our Services include Texture/Orientation, Percent Crystallinity, Crystallite Size and Small Angle Scattering (SAXS).
Polymer Analysis
Orientation of polymer fibers and films is important for improving mechanical, optical, thermal and electrical properties of the materials. Complete pole figures, and functions such as Hermans and White-Sprueill, are used to quantify uniaxial and biaxial orientation states in polymer fibers and films.
Polymer Analysis: Texture/Orientation
Orientation of polymer fibers and films is important for improving mechanical, optical, thermal and electrical properties of the materials. Complete pole figures, and functions such as Herman's Orientation for fibers and White-Sprueill for films or sheets are used to quantify texture strength and direction with respect to the sample directions (MD, TD and N). AMIA Laboratories specializes in polymer diffraction offering many years of experience with PE, PP, PET and Nylon.
Polymer Analysis: Percent Crystallinity
Techniques for % crystallinity measurements on polymers are quite controversial, ranging from discussion on handling oriented materials to background and Compton scattering removal. Location of amorphous regions is also frequently debated. AMIA Laboratories has years of experience working with leaders in the polymer industry in order to develop proprietary techniques to handle % crystallinity in polymer films, fibers and resins.
Polymer Analysis: Small Angle X-ray Scattering (SAXS)
Small Angle X-ray Scattering (SAXS) provides information in another domain, on a macroscopic scale, for long-range ordering or gross features with dimensions in less than 100nm. SAXS can complement WAXS (wide angle X-ray scattering) measurements for a better understanding of the relationship of processing to material properties. SAXS is typically done on polymer materials for lamella spacing or carbons or nano-materials for pore size or particle size.
