METHOD AND SYSTEM FOR EVALUATING CROSSLINKING STATE OF CROSSLINKED MATERIAL

To provide an evaluation method and an evaluation system for the crosslinking state of a crosslinked material capable of efficiently and accurately detecting the overall crosslinking state of the crosslinked material.SOLUTION: Using an ultra-thin sliced piece 20 of a crosslinked material in which a swollen network structure is fixed as a sample, scattering profile data 30 of the sample is acquired by measurement of an X-ray scattering method or a neutron scattering method. Data processing for specifying an intensity curve 40 approximating the acquired scattering profile data 30 is performed by an arithmetic device 3, and a primary particle diameter Rss in the intensity curve 40 is calculated. The calculated primary particle diameter Rss is used as an index to evaluate the crosslinking state.SELECTED DRAWING: Figure 2 【課題】架橋材料の全体的な架橋状態を効率的に正確に把握する架橋材料の架橋状態の評価方法および評価システムを提供する。【解決手段】試料として膨潤させた網目構造が固定化した架橋材料の超薄切片２０を用いて、Ｘ線散乱法または中性子散乱法の測定によりその試料の散乱プロファイルデータ３０を取得し、取得した散乱プロファイルデータ３０に近似する強度曲線４０を特定するデータ処理を演算装置３により行って、強度曲線４０での一次粒子径Ｒｓｓを算出し、算出した一次粒子径Ｒｓｓを指標として用いて架橋状態を評価する。【選択図】図２
