PHYSICOCHEMICAL ANALYSIS – OUR MAIN SKILLS

physico-chemical analyses with nmr at SPECIFIC POLYMERS

Nuclear magnetic resonance spectroscopy – NMR

NMR spectroscopy is a powerful analytical technique for the determination of chemical structures.

This technique is at the heart of our analytical departments. All synthesis reactions, all products and all resin formulations are analyzed by NMR. We have the ability to perform 1H, 13C, 19F, 31P,  COSY, HSQC and  DOSY analysis on our Brucker 300 MHz NMR. This allows us to characterize a very wide range of (macro) molecular products bearing different types of functional groups. NMR spectroscopy enables us, for instance, to evaluate the quality of (macro) molecules, to titrate their functionalities and/or determine the chemical nature of potential impurities. We monitor the reaction kinetics by determining the reaction rate and the potential formation of by-products as a function of time. All final products are thoroughly analyzed in order to validate their chemical compositions, functionality, molecular weight, etc.

Fourier-transform infrared spectroscopy – FTIR

FTIR is a technique used to reveal the functional groups characterizing a given (macro) molecule.

This analysis is used to obtain an infrared spectrum of absorption or emission. It allows for a better knowledge of the chemical structures of synthesized products or raw materials. It can also be used to study the development of chemical structures during a reaction, or to monitor the kinetics of crosslinking reaction during the synthesis of thermosets. In addition to our skills in FTIR analysis, we also have access to a large FTIR spectrum database which makes it possible to go deeper into the understanding of studied products or formulations.

physico-chemical analyses with sec at SPECIFIC POLYMERS

Size exclusion chromatography – SEC

Size exclusion chromatography (SEC) or gel permeation chromatography (GPC) is a common method for determining the average molecular weights and the molecular weight distribution of polymers.

This technique is widely used within the company: to (i) characterize the molecular weights of polymers (Mn, Mw, polydispersity index), (ii) identify the distribution of oligomers, (iii) control the kinetics of polymerization reactions or (iv) study the stability of synthesized polymers (ageing). It can also be used to highlight the evolution of molecular weight that is sometimes observed during the synthesis of various resins. Depending on the polymer solubility, we can perform SEC chromatography either in DMF or THF. Our classical standards: PMMA, PS.

Differential scanning calorimetry – DSC

Differential scanning calorimetry is a thermoanalytical technique used to observe the physical and chemical transformation (glass transition, fusion, crystallization, polymorphism) of a given product, a polymer or a material.

DSC is used to determine the characteristic thermal transitions, study the impact of formulation and/or molecular structure on thermal transitions, achieve kinetic monitoring of the crosslinking reaction of thermosets resin or monitor the effects of ageing. Among these aims, DSC is widely used at SPECIFIC POLYMERS to measure the glass transition temperature (Tg) of synthesized polymers and materials. It is also used to measure both the fusion and crystallization temperatures of some crystalline molecules or polymers. Within the development of thermoset materials, DSC analysis helps to anticipate the curing kinetics and provide interesting information on the curing temperature, gel time or curing reaction exothermicity.

physico-chemical analyses with tga at SPECIFIC POLYMERS

Thermal gravimetric analysis – TGA

TGA is a thermal analysis that measures the loss of weight of a sample as a function of temperature (or time), in a controlled atmosphere.

This technique provides important information that can be used to select materials within a formulation, to predict product performance and improve quality. TGA is mainly used to evaluate the kinetics of the decomposition of materials, predict the temperatures of use and study the thermal or oxidation stability of raw materials and materials. TGA can also be used to evaluate the residual solvent content, residual mass or char yield.

Rheometer

Rheometry is the analytical method used to describe and assess the deformation and flow behavior of materials, i.e. the rheological properties.

Our hybrid rheometer is used in our R&D projects to target development materials or the formulation of coatings, and to monitor the corresponding curing kinetics. One of the main objectives of our measurements is to evaluate the viscosity of resin formulations as a function of the temperature (or shear stress) in order to ensure the compliance of prepared formulations with targeted implementation processes. Rheometer analysis can also provide important information in regard to gel time, pot life or mix viscosity, which are often mandatory for the proper manipulation of these resins.

physico-chemical analyses with contact angle at SPECIFIC POLYMERS

Contact angle

Contact angle analysis is used to quantify the wettability of a solid surface by a liquid.

The contact angle is defined as the angle where the liquid-vapor interface meets a solid interface. This equipment provides the capability to study the wetting of a liquid on a surface through the accurate measurement of the static or dynamic contact angle. Automatic measurement sequencing and video processing allow reliable, fast and reproducible results to be obtained on simple or complex samples. From the polar and dispersive components, we can determine the surface chemical nature of a coating or material (hydrophilic, hydrophobic, super-hydrophobic, oleophilic, oleophobic).

Four-point probe system

The Ossila four-point probe system helps to achieve rapid and reliable measurement of the sheet resistance, resistivity and conductivity of materials.

The system includes a four-point probe in which the probe head uses gentle spring-loaded contacts instead of sharp needles, minimising damage to delicate samples. The four-point probe is capable of delivering currents between 10 nA and 150 mA, and can measure voltages from as low as 100 μV to 10 V. The system can measure sheet resistances franging from 3 mΩ/□ to 10 MΩ/□, enabling the characterization of a wide range of materials and coatings.
