2. Scientists can create a range of new materials to cover a wide range of .

3. Some of these 'designer products are' ...
(i) is material used in sports clothing because it is thermally insulating, waterproof and yet is at the same time.

(ii) is a very used in that can absorb the impact of a knife blade or bullet.

(iii) is an example of an (drawn out threads of a polymer) used to make sports clothing. Its advantage is that it is (not heavy!), strong but when necessary e.g. wetsuits, cyclist sportsware etc. It is a (unreactive) material that is not damaged by sweat, sunlight or detergents. The polymer chain is designed to have that give it strength and springy sections that make it .

(iv) is a very (long molecule) used to coat non-stick frying pans and the manufacture of .

(v) is another that is used in outdoor gear because of its excellent properties and doesn't readily absorb water and is relatively crush resistant.
