Thin films have a number of useful properties, such as low cost, low space, flexibility and usage. They can be used to separate, isolate and protect, such as the ‘cling film’ that is used to wrap food.
A. Use flexible shells and thin films instead of three dimensional structures
- Use inflatable (thin film) structures as winter covers on tennis courts.
B. Isolate the object from the external environment using flexible shells and thin films.
- Float a film of bipolar material (one end hydrophilic, one end hydrophobic) on a reservoir to limit evaporation.
