Abstract This paper presents the experimental analysis of vulcanization process nitrile rubbers for diaphragms fabrication used in FBG-based pressure sensors. Tests using with different rubber thicknesses (0.5mm, 1.0mm, and 1.5mm), temperatures (125°C, 150°C, 200°C), times (2.5min 5.0min) were performed to analyse chemical degradation diaphragms. Degradation was digital macrography diaphragm su...

We address the statistical mechanics of randomly and permanently crosslinked networks. We develop a theoretical framework (vulcanization theory) which can be used to systematically analyze the correlation between the statistical properties of random networks and their histories of formation. Generalizing the original idea of Deam and Edwards, we consider an instantaneous crosslinking process, w...

This work describes a one-step method for the chemical modification of polydimethylsiloxane (PDMS) surfaces. Thin films of ionic and non-ionic surfactants were patterned into an array format, transferred onto silicone pre-polymers, and subsequently immobilized onto the PDMS surfaces during vulcanization. Our results show that while all surfactants tested can render PDMS surfaces hydrophilic thr...

Controllable synthesis and surface engineering of nanomaterials are of strategic importance for tailoring their properties. Here, we demonstrate that the synthesis and surface adjustment of highly stable hierarchical of SnO2 nanospheres can be realized by biomineralization, vulcanization and oxidation techniques. Furthermore, we reveal that the highly stable hierarchical SnO2 nanospheres ensure...

The influence of rubbers, trans-polynorbornene, polyisobutylene P-200 and sevilene on vulcanization characteristics, physical-mechanical dynamic properties rubber used for the manufacture products in contact with sea water has been investigated. It established that developed a sulfur vulcanizing system based rubbers SKMS-30ARK, SKN-4065 BK-1675 additives trans-polynorbornene 11808-340 improved ...

In the processing of nanocomposites, high shear stresses at elevated temperatures orient two-dimensional nanoparticles like graphene. This orientation leads to anisotropic mechanical, thermal or barrier properties nanocomposite. anisotropy is addressed in this study by comparing graphene (few-layer graphene, FLG) with a nanoscaled carbon black (nCB) filler content 3 phr, varying vulcanization, ...
