Nano-structured interpenetrating composites with enhanced Young's modulus and desired Poisson's ratio [PDF]
, 2016 This paper has demonstrated that interpenetrating composites could be designed to not only have an significantly enhanced Young s modulus, but also have a Poisson s ratio at a desired value (e.g. positive, or negative, or zero).

Advanced Functional Materials, EarlyView.Tailored thermo‐mechanical properties of shape memory polymer composites enable large reversible deformation as well as high actuation speed. Moreover, a structural design with curvature in the transverse direction achieves sub‐second actuation on heating and a larger recovery ratio on cooling. Finally, these newly developed smart two‐way actuators can

Effects of Molecular Designs and Double‐Network Morphologies for Bioadhesive Semiconductors
Advanced Functional Materials, EarlyView.This study establishes molecular‐to‐mesoscale design rules for bioadhesive semiconducting polymers (BASCs). It identifies how side‐chain length, double‐network formation, and film thickness modulate adhesion strength and electronic performance, providing insight into the rational design of intrinsically adhesive semiconductors for stable and efficient ...
