“…PFM-AFM allows for the measurements of the adhesion/stiffness of the sample surface via measuring the pull-off force of the tip across the samples surface. Therefore, the PFM-AFM technique has been successfully applied to measure the local stiffness and adhesion properties of a sample alongside the more usual topographic image (29)(30)(31)(32)(33).…”

“…Thermoplastic polyolefin (TPO) refers to a family of blends of isotactic polypropylene (iPP) with various polyolefin such as ethylene copolymers with propylene (EPR), butene (EBR), and others. These polyolefin form a dispersed phase that enhances the physical and mechanical properties of iPP in the solid state 1, 2. Because of their light weight, low cost, good mechanical properties, and relative ease of molding into complex shapes, they have become an important class of materials for the automotive industry 3.…”

Intumescent flame retardant thermoplastic polyolefin (TPO) composites were prepared to study the relationships between their structure of charred layer (including of the multicellular intumescent layer and the charry layer) and flame retardant properties. They were characterized using the LOI and UL-94 test, which indicated that the best fire retardant behavior (V-0 rating and LOI reach to 28.1%) was obtained at the formulation of TPO/ammonium dihydrogen phosphate/starch (100/60/ 20). Thermal gravimetric analysis demonstrated that the presence of ammonium dihydrogen phosphate/starch promoted the esterification and carbonization process in lower temperature range while enhancing the thermal stability of intumescent flame retardant TPO in high-temperature range. Scanning electron microscope and optical microscope were shown that, with combustion time prolonged, the intumescent layers obtained greater number of cells, and the charry layer became more compact while the size of the carbon granules became smaller on the surface. Introduction of starch had an obvious effect on the structure of the intumescent and charry layers. The charry layer of the composites with the content of 20 phr starch was more compact and uniform than that of the composites with 50 phr. The weight ratio of ammonium dihydrogen phosphate to starch in the intumescent flame retardant was fixed as 3 : 1 which cooperated with each other well to promote a compact charry layer and to obtain the better flame retardancy performance. Therefore, the better the charred layers produced, and the better flame retardant properties they obtained.

“…PFM can be used to study nonhomogeneous surfaces of many different materials such as polymer blends, composite materials, or sticky surfaces . This technique has already been used for analysis of photoinduced modification in polymer or sol−gel-based materials. − In this paper, we suggest a significant improvement of the methodology consisting of using plasma polymer deposition for AFM tip functionalization. Using this strategy, the chemical interactions between the tip and the surface are more intense and specific …”

We demonstrate in this paper that plasma polymer can be advantageously used to provide surfaces with topography and chemical control at the nanoscale. Moreover, this technique was also proved to be of high interest to functionalize atomic force microscopy tips that were used to probe the patterned surfaces in pulsed force mode. This approach allowed demonstration by a direct observation of the possibility of generating alternating hydrophilic/hydrophobic surfaces at the nanoscale prepared by DUV laser irradiation. Such a versatile and simple route opens new possibilities in the field of smart surfaces engineering.
