Biography

One of the leading educators in the field of polymer chemistry, Krzysztof (Kris) Matyjaszewski is perhaps best known for the discovery of atom transfer radical polymerization (ATRP), a novel method of polymer synthesis that has revolutionized the way macromolecules are made. As head of the Department of Chemistry, Matyjaszewski formed a research consortium with various industrial corporations to expand the understanding of controlled radical polymerization, including ATRP, and accelerate the transfer of this technology to different commercial applications. A second consortium, formed under his leadership in 2001, continues and expands these efforts, training university and industrial scientists in procedures for responsive polymeric material development. Over 60 companies from Europe, Asia and North America have been members of these consortia.

Harnessing the building blocks of polymer recycling

Phys.org  online

2022-11-01

An alternate route toward a more sustainable polymer industry is to increase the service lifetime of polymers. An intriguing new concept is to impart the ability to "self-heal" from structural damage. Michael Bockstaller, professor of materials science and engineering at Carnegie Mellon University Materials Science and Engineering, in collaboration with Krzysztof Matyjaszewski, professor of chemistry, has discovered that the binding of copolymers on the surface of nanoparticles that are already used in industrial manufacturing provides an economic and scalable route toward self-healing polymers with increased strength and toughness.

Open-air performance for atom transfer radical polymerisation

Chemistry World  online

2020-08-26

Researchers in the US have developed an atom transfer radical polymerisation (ATRP) process that is fully tolerant of oxygen. It will remove the need for specialised equipment and allow users to perform ATRP in both water and organic solvents in an open reaction vessel.

Krzysztof Matyjaszewski is the JC Warner professor of the natural sciences at Carnegie Mellon University in the US. He developed atom transfer radical polymerisation in 1994, a method that is now in wide use throughout the world to control polymerisation. He was talking to Patrick Walter at Iupac’s 47th general assembly in Paris

Fast Bulk Depolymerization of Polymethacrylates by ATRP

ACS Macro Letters

2023

Fast bulk depolymerization of poly(n-butyl methacrylate) and poly(methyl methacrylate), prepared by atom transfer radical polymerization (ATRP), is reported in the temperature range between 150 and 230 °C. Depolymerization of Cl-terminated polymethacrylates was catalyzed by a CuCl2/TPMA complex (0.022 or 0.22 equiv vs P-Cl) and was studied using TGA, also under isothermal conditions. Relatively rapid 5–20 min depolymerization was observed at 230 and 180 °C. The preparative scale reactions were carried out using a short-path distillation setup with up to 84% depolymerization within 15 min at 230 °C.

Synthesis of Hairy Nanoparticles

Hairy Nanoparticles: From Synthesis to Applications

2023

Hairy nanoparticles present a novel platform for the fabrication of hybrid materials with tailored structures and properties. The particular properties of hairy nanoparticles are enabled by the deliberate precision modification of nanoparticle surfaces with polymer chains. Methods based on surface‐initiated controlled radical polymerization (SI‐CRP) have become the most powerful synthetic tool to facilitate the synthesis of hairy nanoparticles. This chapter provides a comprehensive survey of the progress and recent advances in the synthesis of hairy nanoparticles by controlled radical polymerization (CRP) and their characterization.

Highly Conductive Polyoxanorbornene‐Based Polymer Electrolyte for Lithium‐Metal Batteries

Advanced Science

2023

This present study illustrates the synthesis and preparation of polyoxanorbornene‐based bottlebrush polymers with poly(ethylene oxide) (PEO) side chains by ring‐opening metathesis polymerization for solid polymer electrolytes (SPE). In addition to the conductive PEO side chains, the polyoxanorbornene backbones may act as another ion conductor to further promote Li‐ion movement within the SPE matrix. These results suggest that these bottlebrush polymer electrolytes provide impressively high ionic conductivity of 7.12 × 10−4 S cm−1 at room temperature and excellent electrochemical performance, including high‐rate capabilities and cycling stability when paired with a Li metal anode and a LiFePO4 cathode.
