1. Identifify the applications of specialised materials.
2. Describe the production of specialised materials.
3. explain the implications of Nanochemistry.
A specialised material is a substance specially designed for specific usage. It is widely used in various highly sophisticated areas or fields. Some of its notable applications are as follows:
The electronics industry relies on highly specialized materials to make the components it uses in telephones, computers, and other electronic devices. Silicon is a key material in most of these components.
In medical field, dental amalgam is a material mainly specialised for use by dental surgeons to fill cavities in teeth.
In prosthetics, plastic polymer laminates or thermosets are widely used for the fabrication of prosthetic sockets. Common types of plastic polymer laminates used in prosthetics are acrylic, epoxy and polyester. The advantage of plastic laminates is that the prosthetist has a great deal of control over the strength, stiffness and thickness of the finished product.
Specialised polymers are used in concrete repairs to modify cementitious systems or in the form of thermosetting resins, epoxy and unsaturated polyester resins and unsaturated acrylic resin system.
In film industry, the back protectors used for dangerous physical stunts are made from a polypropylene layer for strength, while the shock-absorbing element is often made of expanded polyurethane for maximum comfort and safety.
High tungsten, high carbon- steel tool are special materials used in machine tools and other applications requiring high hardnesss and toughness in the cutting edges of machine.
Most non-stick pans are made using polytetrafluoroethylene, a specialised material for coating designed to prevent food from sticking to their surface during the cooking process.
Because of its energy-absorbing quality, graphite is used to develop high performance sports equipment including golf clubs, tennis racquets, hockey sticks etc.
