Equipements IAM


Specialised in polymer science from the synthesis up to the final application, IAM team is equipped with different techniques to support its research studies.

Mechanical and viscoelastic analyses

AR1000 & AR2000 EX - TA Instruments, MCR102 - Anton Paar
Applications : Characterization of the viscoelastic properties of polymers in solution, molten or solid state according to a large range of possible influence parameters : temperature (thermomechanical behavior), frequency (spectromechanical analyses – master curves), time (kinetic, stress relation, creep…)
Mode : from – 150 °C up to 600 °C : Dynamic, steady or transient mode, Air or inert atmospher
Geometries : parallel plates, cone-plane, couette, rectangular torsion
Contacts : Jean-Pierre Habas & Christine Joly-Duhamel
DMA50 - ACOEM Metravib
Applications : Study of viscoelastic behavior of polymers and composites in the solid state. A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus. The temperature of the sample or the frequency of the stress are often varied, leading to variations in the complex modulus. This approach can be used to locate the glass transition temperature of the material, as well as to identify transitions corresponding to other molecular motions.
Mode : Dynamic from -150°C up to 700 °C with linear or modulated signal, Kinetic, Photocalorimetry (UV) under Hg-Xe lamp
Atmospher : Inert (gaseous nitrogen), Oxydant (air)
Contacts : Abdelatif Manseri & Joel Couve pour la DSC du plateau technique
Formulaction
Applications : Passive Microrheology consists in using micron sized particles to measure the local deformation of a sample due to thermal energy (Brownian motion). This local probing method enables the measurement of the evolution of viscosity and elasticity, in bulk samples or in films.
Contacts : Claire Negrell
Brookfield DV2T
Applications : Viscosimeter measures fluid viscosity at given shear rates
Mode : Room temperature, 0.1 to 200 rpm
Contacts : Vincent Lapinte
Instron 5533
Applications : Mechanical technique for plastics, composites, films
Mode : 100 N and 10 kN sensor, extensometer
Contacts : Vincent Lapinte
