The chemical state of a chemical element is due to its electronic, chemical and physical properties as it exists in combination with itself or a group of one or more other elements. A chemical state is often defined as an "oxidation state" when referring to metal cations. When referring to organic materials, a chemical state is usually defined as a chemical group, which is a group of several elements bonded together. Material scientists, solid state physicists, analytical chemists, surface scientists and spectroscopists describe or characterize the chemical, physical and/or electronic nature of the surface or the bulk regions of a material as having or existing as one or more chemical states.
Method for estimating abrasion resistance
PendingUS20260153456A1Material analysis using wave/particle radiationMaterial testing goodsHigh intensityPolymer composites
Provided is a method for estimating abrasion resistance of polymer composite materials. The present disclosure relates to a method for estimating abrasion resistance, the method including: irradiating a sulfur compound-containing polymer composite material with high intensity X-rays; measuring an X-ray absorption in a small region of the polymer composite material while varying an energy of the X-rays, whereby a dispersion state and a chemical state of the sulfur compound are analyzed; and quantifying an inhomogeneous state of cross-link degradation in the polymer composite material based on the dispersion state and the chemical state.
