Title:  Shape Memory Effect in Polymers
Date & Time: Wednesday, 23rd October 2024 at 4.00 p.m. 
Venue: Rajarshi Bhattacharya Memorial  Lecture Hall, Chemical Sciences Building
Abstract:  
 
Shape memory polymers (SMPs) are innovative smart materials capable of undergoing significant shape transformations and returning to a predetermined permanent shape when subjected to external stimuli. Interest in SMPs has increased due to their straightforward manufacturing and programming processes, making them a cost-effective and efficient alternative to traditional shape-memory alloys. These polymers can recover from both intentional and unintentional deformations by being heated above a specific transition temperature, thanks to the inherent flexibility of their polymer chains. As a type of stimuli-responsive material, SMPs can respond to various external triggers, including light, heat, magnetism, and electricity.
In the presentation, I will be demonstrating the fundamental properties, structures, and mechanisms of SMPs, along with their classification and potential applications across various fields. These applications include minimally invasive surgery, high-performance textiles, and smart materials in space applications, demonstrating the significant role of SMPs in diverse technological and industrial contexts.
