• attenuated total reflectance (ATR)-FTIR spectroscopy
• layer-by-layer (LbL) self-assembly
• diffusion behavior
• two-dimensional (2D) correlation spectroscopy

Attenuated total reflectance (ATR)-FTIR is widely used due to its distinct advantage in studies of polymer films. Layer-by-layer assembly technique is a popular method to prepare ultrathin functional films. ATR-FTIR spectroscopy is introduced here to investigate the structural information of the multilayers without any damage to the samples. Besides, the diffusion process of small molecules, especially water molecules, in the polymer films may be studied carefully by means of ATR-FTIR spectroscopy accompanied by two-dimensional (2D) correlation spectroscopy as a useful tool. In this review, the principle and advantage of ATR-FTIR are briefly introduced and the applications of this effective method in the field of both layer-by-layer assembly technique and diffusion behavior of water molecules in polymer films are discussed.
