Eucommia Ulmoides Gum Soft‐Hard Gradient Composite Materials with Shape Memory Property

Macromolecular Materials and Engineering
Eucommia Ulmoides gum (EUG) is a natural polymer material with unique “rubber‐plastic duality” and good shape memory properties. In this paper, the hardness of EUG is greatly reduced by adjusting the cross‐linking density and adding physical microspheres

Volume changes measurement of elastomers using 3D DIC

Acta Polytechnica CTU Proceedings, 2023
The presented research aims at measuring the volume changes of elastomers using digital image correlation (DIC) in the 3D configuration (stereo DIC). The deformation measurement method in stereo configuration was applied during the mechanical testing of

Vacuum-stripped silicone binder for thermal-control paint [PDF]

, 1973
Silicone elastomer is placed in evacuating system, heated to 160 C and held at this temperature for 24 hours. Elastomer is then cooled to room temperature in vacuum, producing upgraded, low outgassing polymer of increased molecular ...

Self-Sensing Control for Soft-Material Actuators Based on Dielectric Elastomers [PDF]

, 2019
Due to their energy density and softness that are comparable to human muscles dielectric elastomer (DE) transducers are well-suited for soft-robotic applications. This kind of transducer combines actuator and sensor functionality within one transducer so

A rubber-based sensor with over 100 million-level ultra-sensitivity (0–10% strain range) via 3D super-interface

Nature Communications
Constrained by materials, structures, and interface, achieving high sensitivity, wide strain range, and linearity simultaneously remains an impossible triangle for flexible sensors. Herein, we propose 3D super-interface strategy based on patterned rubber

A scanning force microscopy study on the morphology of elastomer-coagent blends [PDF]

, 1993
Atomic force scanning microscopy (AFM) was used to investigate the dispersion of low molecular weight compounds in ethylene-propylene copolymers (EPM). Where other microscopical techniques failed to provide morphological details of this type of blend, as
