Doctoral researcher in electrically and thermally conducting bio-based fabrics for smart textiles

A cross-disciplinary team at Aalto University is looking for a doctoral researcher (Ph.D. candidate) for the Department of Applied Physics to work on conducting lignocellulose fabrics for smart textiles.

The work is done in a project that is part of the FinnCERES Flagship “Redefining the Bioeconomy With advanced bio-based materials” (https://www.finnceres.fi/). In the project, we aim to produce multi-functional conductive bio-based fabrics through an eco-friendly and scalable graphene-based coating without using metals and unsafe chemicals. The target is to achieve good tensile strength, hydrophobicity, fire retardancy, electrical and thermal conductivity, and durability. The research aims to create new opportunities to fabricate high-value-added bio-products, including washable smart textiles with built-in sensors.

Electrically conducting textiles are needed in virtually all eTextile applications. While the project contributes to the development of conducting textile materials in general, the focus is first on electro-thermal applications. The project develops conductive inks containing safe carbon-based materials such as graphene and a suitable polymeric binder. Coated on fabrics, such polymeric conductive coatings do not restrict the bending and flexibility of textiles and resist several cycles of washing and abrasion.

Your role and goals

You will study the functional properties of the coated fabrics and their performance experimentally and theoretically, evaluating the results in view of potential applications. Using structural, electrical, and thermal measurement techniques, including thermal and microscopic imaging you learn to understand how the properties of the materials in the conductive textiles translate to their macroscopic electrical and thermal properties. With your results, you get to provide feedback for improving the material formulations and fabrication methods used in the project.  You will develop knowledge and skills to analyze the electrothermal results with device physics modeling based on the physical properties of the yarns, coatings, and fabrics (structural, electrical, thermal). You will learn hands-on research skills by designing and building measurement rigs for testing the electro-thermal performance of the coated fabric samples for different applications. You will also develop skills to evaluate the technological potential of smart bio-based materials for practical applications and to innovate new applications.

Based on your results, you are expected to write and co-author peer-reviewed journal papers which contribute to the fulfillment of the requirements for a doctoral degree and give conference and seminar presentations. You are also expected to participate in advising B.Sc and M.Sc thesis workers or other student projects on the research topic.

Working group

The working group includes experts from material science, chemistry, and physics. Your focus will be on the physics aspects. You will be affiliated with the New Energy Technologies group at the Department of Applied Physics, School of Science, and supervised by University Lecturer Dr. Janne Halme. You will work in close collaboration with the Textile Chemistry group of Prof. Ali Tehrani, School of Chemical Engineering, Department of Bioproducts and Biosystems.

Janne Halme is a University Lecturer in the Department of Applied Physics at Aalto University. He is a researcher and educator on new energy technologies and solar energy with interests in interdisciplinary research, entrepreneurship education, sustainability, and innovation. His main research field is solar energy physics and engineering, especially colored and printed photovoltaics. Most relevant to this project is his expertise in device physics and performance modeling of energy conversion devices, like photovoltaic and photoelectrochemical cells, impedance spectroscopy, stability studies, and device simulation. He has recent experience with e-textile research from Sun-Powered Textiles project funded by Business Finland (Co-Innovation).

Ali Tehrani is a tenured Associate Professor in the Department of Bioproducts and Biosystems (BIO2) at Aalto University with an educational background in Textile Chemistry and Fiber Science. He is currently leading the Textile Chemistry group at BIO2 which is developing green textile coloration and functionalization. He has worked on several research projects in textile coloration, applied surface chemistry, and electrospun nanofibrous membranes. His recent research work on conductive graphene-based polymer composites, which is published in six peer-reviewed scientific publications, is the ground proof of concept for the project related to this position.
