DESCRIPTION:Dynamic bonds offer a powerful molecular handle for controllin
 g the properties and  functions of polymeric materials. Unlike permanent 
 covalent linkages\, dynamic bonds can exchange in response to their local 
 chemical and physical environment\, allowing molecular-scale processes to 
 influence material behaviour across multiple length and time scales. A key
  motivation for incorporating dynamic bonds into polymers is to enable imp
 roved processability and recyclability. However\, depending on the nature 
 of the dynamic interaction—ranging from dynamic covalent bonds to supram
 olecular interactions—the underlying dynamics and resulting material pro
 perties can vary dramatically. Understanding these relationships creates o
 pportunities for property driven molecular design\, where the chemistry of
  the dynamic moiety is tailored to achieve a desired macroscopic response.
  Beyond processability and recyclability\, dynamic bonds can also impart d
 iverse functional and adaptive properties to polymeric materials. \n\nIn 
 this talk\, I will discuss how subtle changes in the molecular structure a
 nd environment of dynamic moieties can translate into significant differen
 ces in macroscopic material properties. Through examples spanning dynamic 
 covalent and ionic polymeric materials\, I will illustrate how changes in 
 the nature and dynamics of molecular interactions can reshape bulk materia
 l behaviour. Finally\, I will discuss how precise molecular design can int
 roduce new functionality into dynamic polymers\, exemplified by our incorp
 oration of a catchbond effect into polymeric materials\, where dynamic bon
 ds become more persistent under mechanical force.\n\nBio: I am a polymer c
 hemist\, and my research interests primarily lie in designing new polymers
  to replace the present-day commodity plastics with sustainable alternativ
 es. Within this framework\, I am interested in introducing adaptive functi
 onalities into polymers seeking inspiration from biological systems. After
  completing my chemistry bachelor studies\, from Presidency University\, K
 olkata\, I moved to Indian Institute of Technology Kharagpur\, India\, for
  my master’s education in chemistry. There\, as a part of my graduation 
 project\, I worked in the Functional Materials and Electrochemistry Lab\, 
 under the supervision of Prof. C.R. Raj. The research focused on combining
  conducting polymers and mixed transition metal oxides to design flexible 
 supercapacitor devices. I received his master’s degree in 2018. In the s
 ame year\, I started my Ph.D. research in the Supramolecular Polymer Chemi
 stry group at Eindhoven University of Technology under the supervision of 
 Prof. Rint Sijbesma and Dr. Hans Heuts. My research in Eindhoven focused o
 n dynamic covalent polymer networks and I introduced the use of phosphate 
 esters as a dynamic motif in such materials. After my PhD I moved to Wagen
 ingen University and Research for a postdoctoral research period of 2.5 ye
 ars during which I worked with Dr Thomas Kodger and Prof. Jasper van der G
 ucht to design a range of molecular ionic glasses that could potentially s
 erve as sustainable alternatives to polymer glasses. I am currently a post
 doctoral researcher in the Lerch Lab\, at University of Groningen. My rese
 arch in Groningen is focused on two areas: mechanotransduction in soft mat
 ter for force mediated actuation in soft robotics and responsive coating d
 esigns for active delamination leading to efficient material recycling.
