Summary

The human body is composed of composite structures made of water-rich hydrophilic domains and hydrophobic barriers. Combining hydrogels with elastomers results in similar synthetic biomaterials applicable to fields ranging from stretchable electronics to actuators. Here, we report a method to combine hydrogels with elastomers via a glass fiber fabric interphase. The interphase plays two roles: it enables chemically different materials to be robustly bound without chemical treatment while also dramatically improving the mechanical properties of the composite. Maximum interfacial adhesion energies of ∼1,000 N m−1 between the hydrogel and fabric and ∼360 N m−1 between the elastomer and fabric approach adhesion values of chemically bound soft materials. The composite tearing toughness (143 kJ m−2) vastly exceeds that of all neat components. In these materials, Young's modulus is high (∼1.2 GPa), while bending modulus is low (∼7 MPa), resulting in structures that can serve as actuators through controlled solvent exposure.}, number={3}, journal={MATTER}, author={Hubbard, Amber M. and Cui, Wei and Huang, Yiwan and Takahashi, Riku and Dickey, Michael D. and Genzer, Jan and King, Daniel R. and Gong, Jian Ping}, year={2019}, month={Sep}, pages={674–689} } @article{hubbard_davis_dickey_genzer_2018, title={Shape memory polymers for self-folding via compression of thermoplastic sheets}, volume={135}, ISSN={["1097-4628"]}, url={https://doi.org/10.1002/app.46889}, DOI={10.1002/app.46889}, abstractNote={ABSTRACT}, number={47}, journal={JOURNAL OF APPLIED POLYMER SCIENCE}, publisher={Wiley}, author={Hubbard, Amber M. and Davis, Duncan S. and Dickey, Michael D. and Genzer, Jan}, year={2018}, month={Dec} }
