Uploaded by Mia

This dissertation research investigates the properties and engineering applications of polymer-based composites filled with quasi-one-dimensional (1D) van der Waals materials. The study focuses on transition metal trichalcogenides with 1D structural motifs that can be exfoliated into bundles of atomic threads. These quasi-1D van der Waals nanostructures are characterized, and their composite performance is evaluated for relevant electromagnetic shielding, polarization selectivity, and terahertz radiation absorption functions.

UNIVERSITY OF CALIFORNIA RIVERSIDE Properties and Applications of Composites With One-Dimensional van der Waals Materials A Dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Electrical Engineering by Zahra Barani Beiranvand September 2022 Dissertation Committee: Dr. Alexander A. Balandin, Chairperson Dr. Alexander Khitun Dr. Xi Chen Copyright by Zahra Barani Beiranvand 2022 The Dissertation of Zahra Barani Beiranvand is approved: | | | --- | | | Committee Chairperson University of California, Riverside Acknowledgments First and foremost, I would like to express my gratitude to my esteemed supervisor, Professor Alexander Balandin, for giving me the privilege and honor tojoin and work in his laboratories, Phonon Optimized Engineered Materials (POEM) and the Nano Device Laboratory (NDL) . His guidance and advice carried me throughout this research. I am certain without his help, support, and encouragement, I could not have made any progress in my academic career. My gratitude extends to Dr. Alexander Khitun and Dr. Xi Chen for accepting to serve on my dissertation committee. Their immense knowledge and vast experience have always encouraged me in my academic research. My appreciation for Dr. Fariborz Kargar is beyond words. Without his great help in theoretical interpretation and, more importantly, his tea preparation skills, I would not be able to undertake this journey. I am deeply indebted to Dr. Roger Lake, Dr. Sergey Rumyantsev, Dr. Lorenzo Mangolini, Dr. Tina Salguero, Dr. Yassamin Ghafouri, and Dr. Mykhaylo Balinsky, with whom I had the honor of collaborating on different projects. I am extremely grateful to my parents, Ali Barani and Banoo Yavarnezhad, for all their love, care, and sacrifices. I sincerely appreciate my sister, Maryam Barani, my brother, Reza Barani, and my beautiful niece, Afra Kashefi. They encouraged and supported me in every single step toward this path. I would like to express my sincerest appreciation to some of my most influential friends and colleagues: Bahman Kargar, Roghiyeh Vosoogh, Mehrdad Kargar, Marie Balandin, Dr. Vahid Mardanloo, Dr. Saba Baraghani, Dr. Elahe Aghapour, Dr. Salar Rahili, Dr. Evan Wigton-Jones, Sara Shirmohammad, Dr. Ruben Arash Salgado, Dr. Amirmahdi Mohammadzadeh, Dr. Subhajit Ghosh and all the previous and current students in POEM and NDL labs. Finally, many thanks to my best friends, Elahe Babaei, Amin Zanganeh, Dr. Khosro Monsef, Maedeh Taheri, Narges Zarinkamar, Aneseh Mehrak; they are the definition of trust and friendship.
