中文摘要	the diffusion of water in biocompatible semicrystalline poly(lactic acid) (pla) is investigated using time-resolved atr-ftir. there are three different states of water molecules diffusing into the film. using a 2d correlation analysis, the diffusion process and the role of different functional groups on diffusion is obtained. first, the moderately strongly bound water forms a hydrogen bond with -c=o. then, the water diffuses into free volume (microvoids) and strong hydrogen bonds are formed between two -c=o groups and water. the conformations of semicrystalline pla change during the diffusion process and recover after re-drying. in addition, water first interacts with amorphous segments and then interacts with crystalline segments.
