- Adhesion and Cellular Compatibility of Silicone-Based Skin Adhesives
Sarah C. L. Fischer, Klaus Kruttwig, Vera Bandmann, René Hensel and Eduard Arzt
Version of Record online: 22 FEB 2017 | DOI: 10.1002/mame.201600526
The mechanical, adhesive, and biological properties of the two poly(dimethylsiloxanes) Sylgard 184 and Soft Skin Adhesive 7-9800 have been investigated. A special focus is put on the influence of different mixing ratios and substrate roughness. The impact of low pressure oxygen plasma treatment on materials adhesive behavior and biocompatibility has been analyzed.

The optimized electrical, electrochemical impedance, swelling, and mechanical properties for poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) based active layer is given, finding new applications in organic bioelectronics. Such optimal PEDOT:PSS layer used in organic electrochemical transistors shows stability in aqueous media over three weeks and promotes its use for “in vivo” neural applications.
- Engineered Peptide Repairs Defective Adhesive–Dentin Interface
Qiang Ye, Paulette Spencer, Esra Yuca and Candan Tamerler
Version of Record online: 15 FEB 2017 | DOI: 10.1002/mame.201600487
Engineered peptide is utilized to induce remineralization of deficient dentin matrices. Raman spectral images are provided for the original adhesive/dentin interface, the interface with additional etching, and peptide-mediated remineralized interface. Distribution of mineral is observed throughout the interface after remineralization.
- A Newly Designed Dual-Functional Epoxy Monomer for Preparation of Fishbone-Shaped Heterochain Polymer with a High Damping Property at Low Temperature
Yan Li, Jue Cheng and Junying Zhang
Version of Record online: 15 FEB 2017 | DOI: 10.1002/mame.201600574
A new architecture, fishbone-shaped network, is rationally designed by a dual-functional epoxy monomer and polysiloxane. The fishbone-shaped network exhibits an unusual damping property at extreme low temperatures near the Tg of polysiloxane without sacrificing the high tan δ value of the epoxy resins. This discovery supplies a gap of the existing epoxy/polysiloxane materials without outstanding low-temperature damping properties.
- Electrospun Poly(l-Lactic Acid) Nanofibers for Nanogenerator and Diagnostic Sensor Applications
Gengrui Zhao, Baisheng Huang, Jinxi Zhang, Aochen Wang, Kailiang Ren and Zhong Lin Wang
Version of Record online: 9 FEB 2017 | DOI: 10.1002/mame.201600476
Tiny devices with large sensitivity are always what we have been searching for as body sensors. Recently, scientists found that by using electrospinning method, biodegradable poly(L-lactic acid) (PLLA) nanofibers with large piezoelectricity can be produced and the fiber can generate around 20 mV signal under a tiny pressure. Additionally, the PLLA nanofiber can be used as a blood pressure sensor.
