Scanning force microscopy is used in studies of the surface morphology and surface mechanical properties of polymeric solids. Several examples are presented to illustrate that SFM is a powerful and promising tool for investigations, such as, polyethylene single crystal, polymer blend thin films and polymerized organosilane by: Scanning force microscopy is used in studies of the surface morphology and surface mechanical properties of polymeric solids.
Several examples are presented to illustrate that SFM is a powerful and promising tool for investigations, such as, polyethylene single crystal, polymer blend thin films and polymerized organosilane monolayers.
The imaging of nano-mechanical properties, such as, lateral Cited by: The invention of Scanning Tunneling Microscopy (STM) inspired the devel- ment of Atomic Force Microscopy (AFM) and other forms of scanning proximity microscopes in the late s [4, 5].
AFM, unlike STM, can be used to image n- conducting specimens such as polymers. Atomic force microscopy (AFM) belongs to the family of scanning proximity probe microscopy techniques and has developed in the past decades into a versatile and widely used microscopy technique that complements the more traditional techniques of optical microscopy and electron microscopy in studies of by: 2.
It can be found that a nano-microphase structure was obtained by introducing the triblock copolymer to the epoxy matrix following a self-assembly mechanism, and the internal and surface morphology evolution has been evidenced by small-angle X-ray scattering (SAXS), atomic force microscopy (AFM) and transmission electron microscopy (TEM).
With a focus on structure-property relationships, this book describes how polymer morphology affects properties and how scientists can modify them. The book covers structure development, theory, simulation, and processing; and discusses a. Scanning force microscopy (SFM) was used for probing micromechanical properties of compliant polymeric materials.
Classic models of elastic contacts, Sneddon's, Hertzian, and JKR, were tested for various indentation depths and for a variety of polymeric materials. We selected extremely compliant polyisoprene rubbers (Young's modulus, E = 1−3 MPa), elastic polyurethanes (E = 5−50 MPa), and.
Surface morphology study of the EN coatings is carried out by scanning electron microscopy (SEM) (JEOL, JSM) in order to analyze the microstructure of the deposited coatings before and after annealing to see the effect of heat treatment.
SEM is also carried out after tribological testing to see the wear track patterns. Surface morphology and mechanical properties of MDCK monolayers by atomic force microscopy Jan H.

Controlled deformation of polymer surfaces, both reversible and irreversible, with the atomic force microscope, provides a wealth of information about mechanical properties on a nanometer scale. The materials based on alkali metal salts complexed with PEO, known as solid polymer electrolytes, play a critical role to improve the order of conductivity .
Increasing salt concentration, high levels ionic conductivity can be achieved but the major disadvantage of these polymer electrolytes is poor mechanical strength and potential stability.
Afterwards, the influence of these variables on the morphology of the porous structure and the final mechanical properties (i.e., rigidity and damping) was evaluated via scanning electron microscopy and dynamic mechanical thermal analysis, respectively.

So Fujinami. RIKEN SPring‐8 Center, RIKEN, Hyogo, Japan. Scanning Electron Microscopy (SEM) Five samples of EPNCs with different ratios were characterized on their surface morphology through scanning electron microscopy.
Figure 2(a) to Figure 2(e) showed the surface morphology of five samples with different ratios. The combination of 55wt% PVA matrix with PKS and CKS showed.
Polymer Characterization includes determining molecular weight distribution, the molecular structure, the morphology of the polymer, thermal properties, mechanical properties, and any additives. It is a complex and multi-faceted process that should only be done by those with years of experience and strong educational backgrounds--our scientists.
Applications of state-of-the-art atomic force microscopy methods to the elucidation of the surface and near-surface structure of polymeric solids are described. Contact, tapping, force modulation, frictional force, and other modes of atomic force microscopy are described, and recent results are summarized.
Conformational and chain order, crystalline order, polymer crystals, lamellar structures. Over the past 30 years, atomic force microscopy (AFM) has played an important role in elucidating the structure and properties of polymer surfaces.
AFM-based techniques have enabled the quantitative determination of the physicochemical properties of polymer surfaces with high spatial resolution and under a wide variety of conditions.
Coupled with the improvements in spatial and temporal. Elastic and adhesive properties of alkanethiol [CH3(CH2)n−1SH] self-assembled monolayers on gold are investigated by atomic force microscopy and correlated with surface structure via near edge x.
Crystal morphology affects not only all mechanical polymers properties, but may also determine its bio-degradability and bio-compatibility.
In order to successfully control a polymer’s microstructure and achieve the desired properties, a good understanding of polymer crystallization is therefore required. polymer via scanning probe lithography (SPL). Several different lithographies are characterized by the source of the patterned material, whether a mechanical, electri-cal, or thermal ﬁeld is used, and whether the lithography modiﬁes morphology, functionality, or both.
The merits of the different strategies are discussed with respect to. From the reviews: “Atomic force microscopy (AFM) can be used to image polymer surfaces over a broad range from several nanometers to more than micrometer scan sizes.

The observation of phase-separated regions and of polymer crystals lying below a smooth surface shows that not only topography but also elastic. Presenter: Dalia Yablon, Ph.D., Founder, SurfaceChar, LLC Atomic force microscopy (AFM) is uniquely suited to characterize polymer materials on the nanoscale revealing structures and morphology without the need for extensive sample prep or vacuum environment.
Colloid probe atomic force microscopy has also been applied to study the boundary film-forming properties of functionalized viscosity modifier polymers. It is shown that these polymers can form viscous boundary films on rubbed surfaces which produce much lower friction than the corresponding, nonfunctionalised polymers.
