Doctoral candidate Erfan Kimiaei at Aalto University is developing bio-based multiphasic materials for various applications such as barrier packaging, emulsions, foams, cardboard, and textile coatings.
Additionally, his expertise extends to materials' end-of-life scenarios by biodegradation analysis and evaluating the environmental aspects of material production processes through life cycle assessment LCA to promote sustainability and embrace the Circular Economy concept.
In his thesis, he explores the balance between modifying lignocellulose for better performance while still maintaining their biodegradability, even if the product is disposed of inappropriately.
In one of his papers, Erfan used interfacial chemistry to create a hybrid multiphase material, incorporating nanocellulose, lignin nanoparticles, and a biodegradable polymer. Here, Erfan demonstrated that achieving high hydrophobicity for nanocellulose does not necessarily hamper the nanocellulose biodegradability. The developed composite films exhibited unprecedented mechanical properties in both dry and wet states with excellent barrier properties against water vapor, oxygen, UV, and oxidation, which can be highly valuable for packaging applications.
"Working at Aalto, I've had the freedom to pursue impactful research themes and the opportunity to tackle new and intriguing challenges," said Erfan. "I also appreciate the opportunity to closely collaborate with several esteemed global entities including various renowned industry giants, research institutes, and universities spanning across the USA, UK, Canada, Portugal, and Germany."
In the future, Erfan looks forward to working on a larger scale, progressing from lab to pilot and industrial scale. He plans to submit his thesis in soon and complete his doctoral journey by fall 2024.
