As the Poznań Science and Technology Park (PPNT), we are proud to announce that research conducted by our scientists is being published in some of the world’s most prestigious scientific journals.
A research team led by prof. Hieronim Maciejewski delivered a breakthrough project on modern flame-retardant agents, earning recognition from the international scientific community.
Protecting textiles against fire has long been a challenge across many sectors—from the clothing industry to construction and furniture manufacturing.
Naturally flammable materials such as cotton require effective fire protection, while at the same time there is growing attention to the health and environmental safety of the chemicals used.
Until now, many flame-retardant compounds have been based on toxic halogens or formaldehyde, posing risks to human health and the environment.
PPNT’s research team has developed an innovative solution that eliminates these issues.
The new flame-retardant agent, based on compounds containing phosphorus, sulfur and silicon—was created using an advanced chemical process known as the thiol–ene click reaction. As a result, the developed compounds contain no harmful halogens or formaldehyde, and their effectiveness relies on a sol–gel process that forms a durable protective coating on cotton fibres.
The solution reduces the heat release rate by 75%, significantly improving the fabric’s resistance to fire.
Importantly, the coating remains effective even after ten wash cycles, demonstrating its durability and stability in everyday use.
The research results were published in one of the most prestigious scientific journals – Scientific Reports (Nature portfolio) – under the title:
“Synthesis of phosphorus, sulfur and silicon-containing flame retardant via thiol-ene click reaction and its use for durable finishing of cotton fabric”.
This innovative flame-retardant agent is an excellent example of how PPNT supports the development of new, safe and environmentally friendly technologies with real industrial applications. It is another achievement by our scientists, confirming that research carried out at PPNT meets world-class standards.
