Contact Resonance

ABSTRACTA special class of polymer called dendrons which are repeatedly branched polymers linked together by a network of cascade branched monomers. A composite of these dendritic polymers with linear polymers may have unique physical and chemical properties. Using contact resonance mode of atomic force microscopy we are able to detect the viscoelastic properties of the dendritic formation of the polyethylene oxide (PEO) mixed with Polyvinylpyrrolidone (PVP). PEO is known to form nanometric crystallites due to the diffusion limited aggregation process. However, the dendritic formation in the mixture has not been reported before. The amplitude and phase of the contact resonance shows a clear dendritic growth of PEO in the composite material. The extent of the polymer crystallization can be several nanometers thick within the composite material. Additionally, the intrinsic properties of such polymers to form denrimers can be explored for fabricating polymer composites having numerous potential applications in chemical sensing, drug-delivery, energy applications and many more.

Contact Resonance

The self-generation of corrugations on metal surfaces in rolling contact has been studied experimentally in a rolling contact disc machine and theoretically using a computer simulation. The system vibrates in the ‘contact resonance’ mode excited by surface irregularities. If the damping is low and the load high, the vibration may be severe enough to cause plastic indentation of the surface in one revolution which then amplifies the vibration in the next revolution. A stability map has been produced which indicates the ranges of load, damping and surface roughness for which corrugations would be expected to develop.
