Magnetically responsive polymer gels field

In this article, we review recent advances in mechanical and swelling behavior of magnetic field-responsive soft materials, including flexible polymer networks and gels. 

The collapse consists in a strong decrease of the gel volume (by a factor of several tens or hundreds) in response to a small change in the enviroirmental conditions such as temperature, pH, various additives (thermodynamically poor solvent, surfactant, linear polymer), light, electric field, and magnetic field. 

Most smart polymers can be triggered in a variety of ways such as the response of SMPs to thermal, chemical, magnetic and water stimuli. Another example is the way a hydrogel can respond to pH, heat, light, magnetic fields, etc. These diverse stimuli make it possible to use smart polymers in different applications. Smart polymers used in textiles usually appear in various forms such as film, fibre, solution or gel to meet different processing requirements in textiles.
