Surface Treatment & Modification - Consulting, Design and Development

Surfaces cover everything and thankfully with today’s technology we have many options to treat surfaces (chemically, physically…etc.) and modify it in a useful way, with desired outcomes including enhancement of adhesion of coatings or components to surfaces, surface modification for making surfaces hydrophobic (difficult wetting), hydrophillic (easy wetting), antistatic, antibacterial or antifungal, enabling heterogeneous catalysis, making semiconductor device fabrication & fuel cells & self-assembled monolayers possible...etc. Our surface scientists and engineers are well experienced to help you in your design and development efforts of component, subassembly and finished product surfaces. We have the knowledge and experience to determine which techniques to use to analyze and modify your particular surface. We also have access to the most advanced test equipment.

Surface chemistry can be roughly defined as the study of chemical reactions at interfaces. Surface chemistry is closely related to surface engineering, which aims at modifying the chemical composition of a surface by incorporating selected elements or functional groups that produce various desired and beneficial effects or improvements in the properties of the surface or interface. The adhesion of gas or liquid molecules to the surface is known as adsorption. This can be due to either chemisorption or by physisorption. By tailoring surface chemistry, we can achieve better adsorption and adhesion. The behavior of a solution based interface is affected by the surface charge, dipoles, energies, and their distribution within the electrical double layer. Surface physics studies physical changes that occur at interfaces, and overlaps with surface chemistry. Some of the things investigated by surface physics include surface diffusion, surface reconstruction, surface phonons and plasmons, epitaxy and surface enhanced Raman scattering, the emission and tunneling of electrons, spintronics, and the self-assembly of nanostructures on surfaces.

Our study and analysis of surfaces involves both physical and chemical analysis techniques. Several modern methods probe the topmost 1–10 nm of the of surfaces exposed to vacuum. These include X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), low-energy electron diffraction (LEED), electron energy loss spectroscopy (EELS), thermal desorption spectroscopy (TDS), ion scattering spectroscopy (ISS), secondary ion mass spectrometry (SIMS), and other surface analysis methods included in the list of materials analysis methods. Many of these techniques require vacuum as they rely on the detection of electrons or ions emitted from the surface under study. Purely optical techniques can be used to study interfaces under a wide variety of conditions. Reflection-absorption infrared, surface enhanced Raman, and sum frequency generation spectroscopies can be used to probe solid-vacuum as well as solid-gas, solid-liquid, and liquid-gas surfaces. Modern physical analysis methods include scanning-tunneling microscopy (STM) and a family of methods descended from it. These microscopies have considerably increased the ability and desire of surface scientists to measure the physical structure of surfaces.
