Coupling agents
Surface Functionalization
Surface Functionalization provides new properties to the surface of a material. These properties can be physical, chemical or biological. We are focus on chemical surface functionalization via coupling agents.We propose a specific methodology which combines the development of innovative coupling agents with chemical surface functionalization. This approach offers a much broader spectrum of surface functionalities and substrates than other existing methods.
We provide chemical surface modification based on chemisorption. With our surface modification process, the surface properties you expected can easily be controlled and tuned, enhancing the performance and quality of your materials or devices.
Application
BIORECOGNITION
Making the right diagnosis at an earliest stage in the case of illness is crucial. Molecular recognition is central to devices like biosensors and In Vitro Diagnostic kits.
A biosensor is a device incorporating a biological ‘recognition’ element integrated with a physio-chemical transducer.
Many biosensor recognition elements are synthesized in the laboratory. An in vitro diagnostic is a method of performing a diagnostic test outside of a living body. The IVD industry needs reagents that are solutions of highly-specific biological or chemical substances able to react with target substances in the samples.
This process will result in an outcome that can be measured or seen. We offer a large range of coupling agents some of which are well known for biorecognition such as molecules with amine, alcohol, etc. terminal functions and other which are more innovative
ANTICORROSIVE
The serious consequences of the corrosion process have become a problem of worldwide significance. In addition to our everyday encounters with this form of degradation, corrosion causes plant shutdowns, waste of valuable resources, loss or contamination of products, reduction in efficiency, costly maintenance, and expensive overdesign.
It can also jeopardize safety and inhibit technological progress. Given this situation, corrosion protection is a major challenge for many companies. Our solution prevents from corrosion by forming a SAM stable in time and under extreme conditions. The versatile nature of our chemistry means that it can be used either as a discrete layer that is applied prior to the coating, or as a component that is mixed in with a formulation.
CROSSLINKING
The strategy of covalent crosslinking is used in technologies of commercial and scientific interest to control and enhance properties of the resulting polymer system or interface, such as thermosets and coatings. Crosslinking is also the formation of chemical links between molecular chains to form a three-dimensional network of connected molecules. The vulcanization of rubber using elemental sulfur is an example of crosslinking, converting raw rubber from a weak plastic to a highly resilient elastomer. We provide chemicals with two functional groups that can fit with the chemistry of the cross-linked compounds.
ANALYSES
Thanks to a well-equipped technical platform we can quickly characterize :
- The chemical composition of the outermost layer, using X-ray Photoelectron Spectroscopy (XPS)
- The change in thermal properties of the material, using Thermal Analysis (DSC, TGA, DTA)
- The nature of grafted molecules, using 1H, 19F, 29Si, or 31P NMR
- The Morphology, size, nature of a nanomaterial, using Atomic Force Microscopy (AFM)/ Scanning Electron Microscopy (SEM)/ Transmission Electron Microscopy (TEM)
- The specific surface area of materials, using Brunauer, Emett and Teller (BET)
- The size distribution profile of small particles in suspension, using Dynamic light scattering (DLS)
- The structure of compounds, using X-ray diffraction (XRD)
- The wettability of a surface, using Contact angle measurements
- The absorption or emission spectrum at different wavelengths, using UV-visible- Infrared spectroscopy
