反气相色谱(IGC)法作为一种快速、精确和灵敏的方法,近年来在聚合物科学和工程中得到良好应用。介绍了IGC法用于表征聚合物的表面能色散分量、表面酸碱性、结晶度、特征转变温度、Flory-Huggins相互作用参数及小分子在其表面的扩散系数等理化参数的原理、方法及应用,并指出了其未来的发展趋势。
As a fast, accurate and sensitive method, the anti-gas chromatography (IGC) method has been well used in polymer science and engineering in recent years. The principles and methods of IGC for characterizing physical and chemical parameters such as surface energy dispersion, surface acid-base, crystallinity, transition temperature, Flory-Huggins interaction parameters and diffusion coefficients of small molecules on their surface Application, and pointed out its future development trend.
