本文介绍了一种新的表面力装置，它能用中子反射法同时测量吸附聚合物层之间的相互作用力和它们的表面结构。该设备利用两个光学平坦的石英板，通过施加已知的外力将其聚集在一起。表面力和结构配置文件已获得的聚苯乙烯吸附在石英从环己烷，即一个不良的溶剂。
A new surface force apparatus is described which enables simultaneous measurement of the interaction forces between adsorbed polymer layers as well as their surface structure by neutron reflectometry. The apparatus utilises two optically flat quartz plates that are brought together by applying a known external force. Surface force and structural profiles have been obtained for polystyrene adsorbed on quartz from cyclohexane, i.e. a poor solvent.
