Abstract In soft robotics, the fabrication of extremely structures capable performing bio-inspired complex motion is a challenging task. this paper, an innovative 3D printing silicone with embedded shape memory alloy (SMA) actuators are proposed, which completed in single cycle from CAD files. The proposed custom-made setup, based on material extrusion (MEX) method, was used conjunction cartesi...

Impact injuries are commonplace in sport and often lead to performance detriment and debilitation. Personal Protective Equipment (PPE) is prescribed as a mandatory requirement in most sports where these impacts are likely to occur, though the methods of governance and evaluation criteria often do not accurately represent sports specific injury scenarios. One of the key shortcomings of such safe...

Self-healing allows increasing the service life of materials by overcoming some issues caused mechanical failures. We propose a new concept to impart room-temperature self-healing properties thermoplastic elastomers. A macromolecular additive whose interacting units can interfere with hard segments elastomer accelerates chain dynamics and imparts composite material limited detrimental effect on...

Additive manufacturing (AM) is a useful technology to produce artificial aortic models for the training of transcatheter valve replacement (TAVR) surgery. With AM, can be tailored towards individualized anatomy patients. Most these reported so far are manufactured using single rubber-like materials. However, such materials do not replicate mechanical properties natural tissue, especially stress...

background peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. use of silicone may improve outcomes of these repairs. in this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. methods this experimental study w...

Improving the fire-resistant efficiency of silicone-based polymeric coatings is important in building industry and electrical utilities. In this study, water-containing hybrid calcium carbonate (CaCO3)–silica (SiO2) colloidal capsule has been developed optimized as an inorganic flame-retardant additive. This exhibits excellent thermal stability up to 1000 °C with a remaining intact hollow spher...

In this paper, we present the development of a family novel, UV-curable, highly flexible, 3D printable silicone-based materials, mechanical properties which can be tuned simply by varying ratio polymerisable reagents within formulation. This tuneability is achieved exploiting balance between in-cure phase separation and differential reactivity formulation to successfully produce composite struc...

  Despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. Present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. Fifty- four male Wistar rats were divided into three experimental groups (n = 1...

Silicone is already widely used in biomedical applications thanks to its outstanding properties. Now additive manufacturing (AM) of silicone can achieve submillimeter details and offered by SpectroPlast AG as a service. AM particularly interesting for designs with complex internal structures such bioreactors or oxygenators where oxygen permeability important. Therefore, the additively manufactu...

Abstract Silicone rubber is one of the most used outdoor insulation materials in last few decades due to its improved performance contaminated and humid conditions. The silicone insulators their hydrophobic nature, however, organic nature molecules makes them vulnerable ageing degradation. This paper aims at investigating loss recovery hydrophobicity four different micro/nanocomposites exposed ...
