Materials Science and Technology of Polymers at the University of Twente

Ph.D. Thesis in MTP group
What does chemistry mean to you?

 

What would happen to all of humanity if, with a single brushstroke, you wiped out all the contributions of chemistry from modern life? Say goodbye to pharmaceuticals to cure diseases. Forget about trying to log on your computer, turn on the television or send a text message. ‘Chemistry is essential,’ says Professor Julius Vancso, chair of the Materials Science and Technology of Polymers group. ‘Without it, we would all die a lot sooner. ’

The MTP Group of University Twente

The group Materials Science and Technology of Polymers (MTP), chaired by Professor G. Julius Vancso, studies a range of topics, which revolve around macromolecular nanotechnology and materials chemistry of nanostructured (macro)molecular materials.
MTP’s mission is to establish approaches, devise and construct tools, and build materials platforms that enable studies of macromolecular structure, behavior and function from the nanometer length scale, bottom up, in a direct one-to-one control of the molecular objects.
This knowledge is utilized to obtain advanced functional macromolecular materials and devices with enhanced or novel properties and functions for targeted applications.

METALLOPOLYMERS AS RESPONSIVE MATERIALS: SHIFTING EQUILIBRIUM BY TUNING STRUCTURE

This Thesis describes the synthesis and characterization of a series of poly(ionic liquids) (PILs), or polyelectrolytes, from poly(ferrocenylsilane)s (PFSs) and their applications in responsive materials. PFSs are a fascinating class of metallopolymers, with a backbone consisting of alternating ferrocene and silane units. Redox-active ferrocene units provide unique redox-responsive properties, and the presence of silane groups offers great opportunities for post-polymerization modification. By tuning polymer structures and compositions, and applying external fields or constraints under appropriate processing conditions, a variety of applications are explored in this Thesis, including artificial muscles from electrospun hydrogel microfibers, porous membranes and micro-particles with breathing pores, an active plasmonic system from AuNP-hydrogel composites, CNT-hydrogel composites with bi-stable states and tunable resistance, an electrically switched smart window device, and symmetric redox flow batteries.

The annual Global Young Scientists’ Summit (GYSS) took place 15 - 20 January 2017 at the Singapore University of Technology and Design (SUTD). The summit has a mission to engage early career researchers with Nobel Laureates, Field Medalists, Millennium Technology Prize winners, and Turing Award winners. Over 250 of the world’s most outstanding PhDs and post-doctoral fellows in the field of STEM (Science, Technology, Engineering and Mathematics) had a chance to be inspired by the enthusiasm, determination, and persistence of the eminent scientists through plenary lectures, panel discussions, and interactive small group sessions.

During the summit, young researchers found an opportunity to visit  Singaporean universities (National University of Singapore, Nanyang Technological University, Singapore University of Technology and Design). In addition, they also visited research centers (Agency for Science, Technology and Research (A*STAR), Campus for Research Excellence and Technological Enterprise (CREATE)) which provided an insight into the research facilities and available opportunities in Singapore.

The program also included site visits to Deep Tunnel Sewerage System, PSA Corporation Limited, Housing & Development Board and Tuaspring Desalination Plant. Those visits proved that Singapore is a unique example of a country that has a vison to integrate scientific innovations for the benefits of society.

New UT measurement technique uses tiny amounts of protein


Barnacle’s larvae leave behind tiny protein traces on a ship hull: but what is the type of protein and what is the protein-surface interaction? Conventional techniques can only indentify dissolved proteins and in large quantities. Using a modified type of an Atomic Force Microscope, scientists of The University of Twente in the Netherlands and A*STAR in Singapore, can now measure protein characteristics of even very small traces on a surface. They present the new technique n Nature Nanotechnology.
