Actuation of shape-shifting materials has typically required an external trigger. Here, the authors design a shape-memory hydrogel, regulated by a dual network of covalent and temporary hydrogen bonds, whose actuations are encoded by an intrinsic tem

We prepared nonflammable liquid polymer electrolytes for lithium-ion batteries by mixing ethoxylated perfluoropolyethers (PFPEs) with LiN(SO2CF3)2 salt. Interestingly, we identified the presence of chain coupling in the PFPE polymers and their functi

Core–shell molecular bottlebrushes with various topologies and with poly (tert-butyl acrylate)-b-polystyrene (PtBA-b-PS) block copolymer side chains were synthesized via atom transfer radical polymerization (ATRP). After hydrolysis of the PtBA segm

The structural details of bottlebrush polymers, specifically the grafting density and molecular weight distribution of side chains, influence their physical properties; however, they are difficult to analyze using conventional techniques. Herein we r

Electroactive Polymer Actuators and Devices (EAPAD) 2017.
Electroactive polymers (EAPs) refer to a broad range of relatively soft materials that change size and/or shape upon application of an electrical stimulus. Of these, dielectric elastomers (DEs) generated from either chemically- or physically-crosslin

Electroactive Polymer Actuators and Devices (EAPAD) 2017.
Dielectric elastomers (DEs) are the leading technology for artificial muscles due to a favorable combination of large stroke, fast response, and high energy density. However, at large actuations, DEs are prone to spontaneous rupture from electromecha
