Smart World; Smart Polymers

Welcome to the timely publication of this chapter entitled: ¿Smart World; Smart polymers¿. Smart polymers, stimuli-responsive polymers or functional polymers are high-performance polymers that change according to the environment they are in. Such materials can be sensitive to a number of factors, such as temperature, humidity, pH, chemical compounds, the wavelength or intensity of light or an electrical or magnetic field and can respond in various ways, like altering color or transparency, becoming conductive or permeable to water or changing shape (shape memory polymers). Usually, slight changes in the environment are sufficient to induce large changes in the polymer's properties.I think the coming decades will be the years of the emergence and growth of smart polymers; So that in all everyday events we see the role of one of them! So it is not in vain to say after a thoughtful study in the field of smart polymers:¿Welcome to the new era of materials!¿
