The dynamical behaviour of an entangled network, a melt made of long polymer chains, with an oscillating nanotip, is investigated to provide evidence for a close relationship between the spatial scale and dynamics of the network, from the molecular t

This experimental work aims to show that the Q factor value is an experimental parameter of great importance to access different soft materials properties with a dynamic Atomic Force Microscope. Two dynamic modes have been compared, amplitude modulat

Dynamic force microscopy is known for its ability to image soft materials without inducing severe damage. For such materials, the determination of the relative contributions of the topography and the local mechanical properties to the recorded image

This work is an attempt to investigate viscosities at the nanometer scale. To do so, the tapping mode atomic force microscopy is used on a triblock copolymer exhibiting a well-defined periodic structure at the nanometer scale. Variations of the oscil

The present work investigates the role of the adhesion in the oscillation behavior of a tip cantilever system when soft materials are studied. To do so, the attractive interaction between a sphere and a concave surface is calculated with the aim of p

In atomic force microscopy, tapping-mode (also called intermittent contact mode) operation is known for its ability to image soft materials without inducing severe damage. For soft materials, the determination of the relative contributions of the top

We present an experimental study of a triblock copolymer with the AFM non contact resonant mode. This dynamic force microscope allows the attractive tip surface interaction to be finely tuned by varying the shift of the resonance frequency. The tribl

The Navier-Stokes equation is used to analyze the additional phase delay when an oscillating nanotip touches intermittently an entangled polymer melt. Even when the tip oscillates at frequencies of several hundred kilohertz, it is shown that the iner
