摘要(Abstract)：

【目的】从亲疏水特征的角度对贝壳各层次结构中的界面进行分析探讨。【方法】采用接触角测量仪对贝壳的中维界面、无机文石及无机方解石进行水接触角测量。【结果】贝壳内表面的水接触角普遍大于90°,其中最大值为113°,最小值为91°;贝壳表壳层内表面边缘位置的水接触角平均值为67°,内部位置的水接触角平均值为112°;无机文石及无机方解石平整表面的水接触角均小于90°,其平均值分别为50°、49°。【结论】贝壳内表面具有疏水性,即有机质层具有疏水性;由于具有亲水特征的文石及方解石为贝壳矿物的主要成分,说明贝壳矿物结构具有亲水性;贝壳表壳层内表面边缘呈现亲水特征,内部呈现疏水特征。
