Lecture on solution processed 2-dimensional materials

 

Lecturer: Tawfique Hasan, University of Cambridge

Summary:

This three-hour lecture will be divided into two sections. In the first section, we will cover solution phase production of graphene and related layered materials (GRMs).

In the second section of the lecture (50 mins), we will discuss application requirements of next generation transparent conductors and where graphene might fit into the picture.

Tentative outline of the lecture:

Section 1: ~1:45 hrs

       Solution phase production of GRMs

      Liquid phase exfoliation (UALPE)

       Basics of cavitation for Ultrasonic Assisted Liquid Phase Exfoliation (UALPE)

       High pressure homogenization

       Solvent only exfoliation

      Properties of solvents

       Surfactant assisted exfoliation

      Graphene Oxide

       Functionalization

      Electrochemical Exfoliation

      Chemical Synthesis

       Deposition of Solution phase produced GRMs

      Common considerations for Printing, Coating and Composites

       General comparison between different production methods

Section 2: 0:50 hrs

       Transparent conductors

       Figure of merit

       Current generation oxide-based conductors (TCOs)

      Limitations

      Mechanical loading and stresses on thin TCOs

       Nanostructured transparent conductors

      Nanotubes

      Metal nanowires

      Graphene/Graphene Oxide

      Comparison between next generation transparent conductors
