Carbon recycling instead of plastic trash

Iron electrocatalysis breaks down polystyrene and delivers green hydrogen

14-Nov-2024 - Plastics are inescapable in our daily lives. The vast amounts of plastic garbage heaped in landfills and in the environment, however, are as problematic as the plastics are useful. In the journal Angewandte Chemie, a German research team has now introduced a new method for recycling polystyrene ...

Adhesive Comes Unglued on Command

Oxidation triggers debonding of mussel-inspired adhesive

23-Sep-2024 - Modern integrated microelectronic devices are often poorly repairable and difficult to recycle. Debondable adhesives play a key role in the transition to a circular economy with sustainable resources, less waste, and intelligent repair/recycling strategies. In the journal Angewandte Chemie, a ...

Repellant and Hostile to Bacteria

Zwitterionic polymeric sulfur ylides: antifouling coating with a synergistic effect

13-Sep-2023 - Bacteria that gather into biofilms on the surfaces of implants, catheters, breathing tubes, and other medical components are a serious health hazard. In the journal Angewandte Chemie, a research team from the Netherlands has now introduced a new material based on poly(sulfur ylides) that—when ...

Trojan Horse Polymers for a Circular Economy

New strategy for recyclable polyolefins

21-Jun-2023 - It is hard to imagine our daily lives without plastics made out of polyolefins. Unfortunately, practical methods for recycling of polyolefins are lacking. In the journal Angewandte Chemie, a research team has now introduced a new approach for making novel polyolefins that can be chemically ...

Two Worlds, One Material

Polymers with a metal backbone

08-Feb-2023 - Until now, it has been clear: you can have a metal or a plastic, but not both in one. However, things don’t have to stay that way. In the journal Angewandte Chemie, a Chinese research team has now reported a polymer with a metallic backbone that is conductive, thermally stable, and has ...

Economical PEF Production

Efficient titanium-based catalyst used to produce PEF, the biobased alternative to PET

30-Aug-2022 - One possible replacement for drink containers made from PET is polyethylene furandicarboxylate (PEF), made from renewable resources. However, the production of the raw material for PEF from biomass is still rather inefficient. A new titanium-based photocatalyst could be about to change this, ...

Upcycling with light: Biomass-derived crosslinked polymers

14-Jun-2022 - From inexpensive mass products to tailored high-tech materials, our modern world without plastics is unimaginable. The major downside to this is the use of fossil fuels and the growing quantities of waste. A new approach could be the production of high-grade plastics made from biomass that could ...

Polymers with Helical Blocks

Forming domains in supramolecular polymers using UV irradiation

02-Dec-2021 - Polymers, the basis of all plastics, usually do not have an ordered structure, in contrast to biopolymers such as proteins. A team of researchers has now developed a polymer that can be differentiated into folded (ordered) and unfolded (disordered) domains using UV irradiation. The team’s work ...

Degradable sugar-based polymers may store and release useful molecular freight

Options for chemical plastic recycling

25-Jan-2021 - Degradable, bio-based polymers offer options for chemical recycling, and they can be a tool to store and release useful molecules. Scientists have developed a class of sugar-based polymers that are degradable through acid hydrolysis. The researchers also integrated “cargo” molecules in the ...

Ultraheavy precision polymers

Controlled photoenzymatic RAFT polymerization of nonconjugated polymers

30-Oct-2020 - An environmentally friendly and sustainable synthesis of "heavyweight" polymers with very narrow molecular weight distributions is an important concept in modern polymer chemistry. Thanks to a new photoenzymatic process, Chinese researchers have been able to increase the range of possible ...
