摘要
A film balance for the investigation of insoluble monolayers at the macroscopic oil-water interface is described. The design of the balance enables simultaneous surface tension and optical reflection measurements under well defined conditions. The oil-phase is contained within a quartz housing whose dimensions are optimized for imaging purposes. The performance of the apparatus is illustrated by the pi, A-isotherm of a phospholipid and ellipsometric images of the morphology of the phospholipid dipolmitoyl-phosphatidyl-ethanolamine at the hexadecane-water interface.
