Накратко на български

Железни катализатори се използват за създаване на нови полимери от растителни вещества, като например бета-мирцен. Това помага за замяната на скъпите и токсични метали с достъпни алтернативи и намаляване на зависимостта от петролните ресурси.

Constructing functional polyolefins through an iron catalyzed one-pot POLYmerization FUNctionalization strategy

The modern chemical industry is facing a dual challenge: the urgent need to transition from fossil-based resources to renewable feedstocks and the requirement for more sustainable, cost-effective catalytic processes. Most current industrial plastic production and chemical transformations rely on expensive, and often toxic, noble metal catalysts. This project was born from the necessity to replace these systems with earth-abundant, non-toxic, and inexpensive transition metals, specifically focusing on iron-based catalysis. The primary objective of the research was to develop a versatile chemical "toolbox" based on iron complexes to transform both traditional olefins and bio-derived molecules into high value functional materials. By using natural terpenes, such as beta-myrcene, which can be extracted from plants, the project aimed to create a new generation of bio based polymers. This approach directly addresses the European strategic priority of the Circular Bioeconomy, which seeks to reduce carbon footprints by substituting petroleum-derived components with sustainable alternatives. The project pathway to impact was designed to bridge the gap between fundamental organometallic chemistry and practical materials science. The motivation was not only to synthesize new polymers but to understand how changing the metal center could radically alter the internal structure and properties of a polymer. This level of control is crucial for designing materials with specific mechanical and thermal characteristics for industrial applications, ranging from high-performance elastomers to sustainable coatings.

Цел на проекта

We are in an era of demand for new, high-performance and sustainable plastics. The challenge is to counterbalance the actual need of society for disposable devices without compromising the sustainability of the overall production. Within the polymer field, polyolefins account for more than 50% of global plastics demand. However, their main drawback is represented by their hydrophobicity and their poor applicability in blending, adhesion and dyeing due to a lack of functional groups. In this regard, one fundamental challenge is to develop a new strategy that combines polymer synthesis and the incorporation of polar moieties into polyolefins. Within this context, POLYFUN seeks to deliver functional polyolefins by employing a single iron-based catalyst to perform two subsequent catalytic steps in a one-pot strategy. This approach, although being an important tool at the molecular level, has not yet found any application in the polymer field to access materials with intriguing and robust properties in one single process. From a scientific and technological perspective, POLYFUN intends to fabricate functionalized polymers with tunable and unique properties with an innovative approach in the field. This project is highly interdisciplinary, involving different research areas such as organic chemistry, catalysis, and material science. As such, it is envisioned that the development of this new strategy can generate breakthrough scientific papers, valuable discoveries and/or potential patents. This fellowship brings a two-fold transfer of knowledge: advanced techniques in organic chemistry to the host institution and material chemistry to the fellow. Overall, the project’s multidisciplinarity and intersectoral nature will broaden the fellow’s competencies and will place her in a competitive position for her next career move.
