Enhancement the conductivity and flexibility of fabricated chip comprise from nano graphene metals assembled on polymeric PEI- PDMS matrix
This work aims to make a unique polymer to be used as a conductive and flexible chip antenna. Its properties are robustness, rigidity, stretchability, and good conduction. The fabricated composite is composed of two copolymers, Polydimethylsiloxane (PDMS) and Polyethylenimine (PEI), assembled with nano metals (Copper, Silver), and graphene nanoparticles as a matrix. Nano metals fill out the inter-layer space, and polymer voids reinforce the cross linker. Graphene/metal nanoparticles help make chelating complexes using metallic bonds, enhancing the polymer’s conductivity from 1.87 × 10-4 to 5.64 ×10-6 σ Scm-1. The conductivity, self-healing, and surface morphology of fabricated composite are analyzed using different spectroscopic techniques, such as electrochemical impedance (EIS), Scanning Electronic Microscopy (SEM), Transition Electronic Microscopy (TEM), Infrared spectroscopy (IR), UV-Visible spectroscopy (UV), and a particle size analyzer.
期刊介绍：
Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
