Solvent Responsive Shape Memory Polymers‐ Evolution, Current Status, and Future Outlook

Abstract

Solvent responsive shape memory polymers are smart shape morphing materials that can recover from a fixed shape when stimulated with solvents. Unlike thermally responsive shape memory polymers, these materials have numerous unique advantages that enabled them to grab the attention of the scientific community. Since early 2005, with the inception of the solvent-induced recovery process, the shape memory polymer realm continued to evolve to circumscribe this novel stimulus. With this backdrop, this review attempts to highlight the development and the growth of solvent responsive shape memory polymers along with its recent trends. After introducing the concept of shape memory polymers, the review introduces how the idea of solvent-induced shape memory polymer stemmed along with describing how the response behavior works. A variety of polymer systems are introduced that respond to water and various solvents together with their emerging application in biomedicine and typical sensing operations. Finally, the potentials and the future outlook for improvement are reviewed.

Additive manufacturing of smart polymeric composites: Literature review and future perspectives

“…Current challenges with moisture‐activated SMPs are hydrolytic stability, flexibility, and antifungal property, which are addressed by novel polymer chains of polytetrahydrofuran and polycaprolactone assisted with polyacrylic acid. [ 148 ]…”

A Novel Microscopic Modeling Scheme for the Shape Memory Polymer Composites with respect to the Ambient Temperature

“…On this basis, the effective modulus of each lamina can be obtained by employing an effective microscopic mechanical model. (2) The SMPC consists of a series of unidirectional laminas. Therefore, the effective elastic modulus and mechanical property of the SMPC can be acquired by employing the classic laminate theory.…”

“…Due to its unique molecular structure and good performances, including light weight, low cost, and high strain recovery rate, shape memory polymer (SMP) exhibits a widespread prospect in medical, energy, and electronic communications [1,2]. It is reported by Leng et al [3] that the maximum strain of the SMP reach to 600%.…”

Two‐Way Semicrystalline Shape Memory Elastomers: Development and Current Research Trends

“…[1,6] In this backdrop, smart materials have developed the ability to undergo shape changes between two or more shapes when activated with a stimulus (e.g., cycling heating or cooling over a range of temperatures). [7][8][9][10][11] The temporary shape, in the case of any smart material, is a metastable state, and an application of an induced trigger quickly induces the metastable state to return to a more stable state. Shape memory materials are a very special class of smart materials that possess the capability of memorizing a temporary/metastable state and trace back to its permanent/stable state when triggered with an appropriate stimulus.…”
