Revolutionary Waterproofing Technology: Protecting Clothes and Equipment

The video discusses the limitations of existing waterproofing methods and introduces a new technique developed by PhD student Stephen Coulson. His method uses an ultra-thin polymer applied through a plasma processing machine, making materials like fabrics and electronics waterproof without altering their properties. Initially used by the military, this technology is expected to be available commercially, potentially revolutionizing waterproofing in various industries.

What was the main issue with existing waterproofing methods before Stephen Coulson's innovation?

• They were difficult to apply.

• They damaged the fabric.

• They were not effective enough.

• They were too expensive.

What is the thickness of the polymer coating developed by Coulson?

• 1 millimetre

• 1 nanometre

• 1 centimetre

• 1 millionth of a centimetre

How does the plasma processing machine apply the waterproof coating?

• By dipping the fabric in a chemical bath

• By introducing a low pressure vapour

• By spraying a liquid solution

• By using high temperature

What is a key benefit of the fabric after being treated with Coulson's waterproofing method?

• It becomes fire-resistant.

• It feels like plastic.

• It becomes more colorful.

• It remains breathable.

Which materials, besides fabrics, can be waterproofed using the plasma process?

• Only ceramics

• Only plastics

• Plastics, glass, ceramics, and metals

• Only metals
