What are nanochemicals?
are chemical substances or materials that are manufactured and used at a very small scale (down to 10,000 times smaller than the diameter of a human hair).
are developed to exhibit novel characteristics (such as increased strength, chemical reactivity or conductivity) compared to the same material without nanoscale features.
Smart Material
Smart materials can be regarded as materials that respond to a change of temperature, humidity, contact with water, electrical current or other inputs.
They usually change in terms of colour or shape when responding to an input.
