Effect of thermal annealing on ferroelectric domain structures in poly(vinylidene-fluoride-trifluorethylene) Langmuir-Blodgett thin films" (2014). Stephen Ducharme Publications. Paper 95. We report a piezo-response force microscopy study of the effect of thermal annealing on ferroelec-tric domain structures in 6 to 20 monolayer (11 to 36 nm) polycrystalline poly(vinylidene-fluoride-trifluorethy...
The aim of this work was to determine the influence of the biomaterial environment on human mesenchymal stem cell (hMSC) fate when cultured in supports with varying topography. Poly(vinylidene fluoride) (PVDF) culture supports were prepared with structures ranging between 2D and 3D, based on PVDF films on which PVDF microspheres were deposited with varying surface density. Maintenance of multip...
In this paper, a 60 nm-thick ferroelectric film of poly(vinylidene fluoride–trifluoroethylene) on a flexible substrate of aluminum foil was fabricated and characterized. Compared to pristine silicon wafer, Al-foil has very large root-mean-square (RMS) roughness, thus presenting challenges for the fabrication of flat and uniform electronic devices on such a rough substrate. In particular, RMS ro...
Sequencing of the human genome reveals that there are approximately 30,000 genes that encode an even greater number of proteins which comprise the human proteome. Characterization of gene products at the genome-wide scale requires the development of high throughput methods to generate temporo-spatial information on each and every protein in the cell under normal and pathological conditions. Mon...
The paper presents the results of a study effect temperature and relative humidity environment on structure microporous films copolymer P(VDF-TrFE) obtained by phase-inversion method. It is shown that with increasing pore size film increases, while leads to their reduction. optimal range external environmental conditions for obtaining porous honeycomb pattern proposed. influence different solve...
Piezoelectric polymers have emerged as promising materials for application in pressure sensing devices particular wearable applications, where inorganic piezoelectric can face limitations due to their brittleness. One of the bottlenecks adaptation is relatively weak voltage coefficient. Hence there been numerous efforts improve performance comprising by making composites poly(vinylidene fluorid...
