Examples of smart polymers
WebFeb 6, 2024 · What are smart polymers with examples? The most common types of smart polymers are: Thermoresponsive polymers: Polymers that change their properties in response to changes in temperature. An example of this is poly(N-isopropylacrylamide) (PNIPAM), which is a hydrophilic polymer that is soluble in water at temperatures below … WebSmart polymers They are high-performance polymers that change according to the environment they are located. Such materials can be sensitive to a number of factors, such as temperature, humidity, pH, wavelength, intensity of light or magnetic field and can respond in different ways, like altering color or transparency.
