Dr. Pingwei Liu, our emeritus group member who received his Ph. D. degree at ZJU in 2014, and is now pursuing his post-doctoral research under the supervision of Prof. Strano in the Department of Chemical Engineeing at MIT, published one paper in Science. The paper “Layered and scrolled nanocomposites with aligned semi-infinite grapheme inclusions at the platelet limit” appears in the current issue of Science. Please see Science, 2016, 353(6297): 364-367. [doi: 10.1126/science.aaf4362] for details.

Two-dimensional (2D) materials can uniquely span the physical dimensions of a surrounding composite matrix in the limit of maximum reinforcement. However, the alignment and assembly of continuous 2D components at high volume fraction remain challenging. Liu etc. use a stacking and folding method to generate aligned graphene/polycarbonate composites with as many as 320 parallel layers spanning 0.032 to 0.11 millimeters in thickness that significantly increases the effective elastic modulus and strength at exceptionally low volume fractions of only 0.082%.These composites promise substantial mechanical reinforcement, electrical,and optical properties at highly reduced volume fraction.
