The ideal drug delivery system is the Feb 25, 2013 Polymeric materials, therefore, become stimulus-responsive when the entanglements that define them are stimulus-responsive. Typically, Apr 20, 2017 SC5: Stimuli-Responsive Polymers · Dissolved in or phase-separated out of aqueous solutions · Adsorbed onto aqueous-solid interfaces Responsive polymer materials can adapt to surrounding environments, regulate transport of ions and molecules, change wettability and adhesion of different Several receptors on the body recieve external inputs, such as pain or tast, and respond with a coordinate action. In addition to elastomers, hyperelastic material models are also used to approximate the material behavior of biological tissues, polymeric foams, etc. Linearly Jan 3, 2020 New types of 2D and 3D stimuli‐responsive materials can be properties, which are inspiring the next generation of smart materials. Stimuli-responsive polymers are defined as high-performance polymers that can change in accordance with the environment they are subjected to. For systemic Stimuli Responsive Polymers. Stimuliresponsiva polymerer.
Smart polymers, stimuli-responsive polymers or functional polymers are high-performance polymers that change according to the environment they are in. Names coined for ‘stimuli-responsive’ polymers have been given as stimuli-sensitive , intelligent , smart , , or environmentally sensitive polymers . These polymer systems might recognize a stimulus as a signal, judge the magnitude of this signal, and then change their chain conformation in direct response [1] . Polymers that can respond to external stimuli are of great interest in medicine, especially as controlled drug release vehicles. In this critical review, we consider the types of stimulus response used in therapeutic applications and the main classes of responsive materials developed to date. Responsive polymer materials can adapt to surrounding environments, regulate transport of ions and molecules, change wettability and adhesion of different species on external stimuli, or convert chemical and biochemical signals into optical, electrical, thermal and mechanical signals, and vice versa. The effects of branching on stimuli responsive polymers are an important issue since the polymer topology can have a significant influence on the response behavior.

Stimuli-responsive polymers undergo dramatic and abrupt physical and chemical changes in response to external stimuli [2]. They are also termed ‘smart-’ [3, 4], ‘intelli-gent-’ [5], or ‘environmentally sensitive’ polymers [6]. One important feature of this type of material is reversibility, 2018-09-18 Classes of stimuli-responsive polymers based on their physical forms.

Stimuli-responsive polymers or so-called “smart polymers” are macromolecules that are sensitive to certain triggers from the external environment, including …
Stimuli-responsive polymers or macromolecules also exhibit the ability to convert biochemical and chemical signals into mechanical, thermal, optical, and electrical signals, and vice versa, for which they are utilized in an array of applications like “smart” optical systems, drug delivery, diagnostics, and tissue engineering, in conjunction with coatings, textiles, biosensors, and microelectromechanical systems.
