C change is a waterproof and windproof temperature adaptive material developed and produced by Schoeller Textiles. [1]The material contains a membrane layer which is set to a predetermined temperature range.
Another is a humidity-sensitive polymer used in self-adaptive wound dressings that automatically regulate moisture balance in and around the wound. [5] [6] The nonlinear response of smart polymers is what makes them so unique and effective. A significant change in structure and properties can be induced by a very small stimulus.
PDF/X is formalized in ISO standards 15929 and 15930: ISO 15929 (which was withdrawn in March 2008 and no longer is an official standard) specified the guidelines and principles for the development of PDF/X standards.
Smart materials, also called intelligent or responsive materials, [1] [page needed] are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, moisture, electric or magnetic fields, light, temperature, pH, or chemical compounds.

These crystallites form covalent netpoints which prevent the polymer from reforming its usual coiled structure. The hard to soft segment ratio is often between 5/95 and 95/5, but ideally this ratio is between 20/80 and 80/20. [12] The shape-memory polymers are effectively viscoelastic and many models and analysis methods exist.
