A multimode immersion cooling system includes a first, single-phase immersion cooling mode and a second, two-phase immersion cooling mode. The system operates in a single phase mode and reserves a two-phase mode for peak energy consumption periods. A single thermal transfer fluid is used for both modes, remaining in a liquid phase in a first single-phase immersion cooling mode and vaporizing when the thermal transfer fluid temperature reaches its boiling point in a second two-phase immersion cooling mode. A heat exchanger extracts thermal energy from heated thermal transfer fluid in the single phase mode while a condenser cools vaporized thermal transfer fluid to condense the vapor during the second, two-phase immersion cooling mode. A controller determines whether the multimode immersion cooling system operates in the single-phase mode or the second two-phase mode, or both.

In some embodiment, the introduction of hydration layer to the base plastic through the intermediate plastic imparts germ repellency by introducing sufficient hydroxyl groups onto the surface of the base plastic in order to trap water molecules into a polymer matrix of the base plastic. The change in mechanical strength of the base plastic before and after the introduction of the hydration layer is less than 20% of an original mechanical strength, where the original mechanical strength corresponds to a strength of the base plastic before formation of the hydration layer.
