Macroscopic film

{
  "id": "MLC-T-CHM-006892",
  "term": "Macroscopic film",
  "field": "Chemistry",
  "definition": "A film whose lateral dimensions exceed 100 micrometres, giving a continuous layer on a macroscopic scale. The name describes extent across the surface, not thickness, so a Langmuir monolayer spread on a trough, only one molecule thick, still counts as macroscopic when it is wide enough. It contrasts with a microscopic film, whose lateral dimensions lie between 0.1 and 100 micrometres.",
