The process of electrospinning polymer solutions depends on many entry parameters, with each having a significant impact on the overall process and where complexity prevents the expression of their interplay. However, under the assumption that most p

Antibacterial Filtration Membranes Based on PVDF

Autor: Petra, Peer, Magda, Janalikova, Jana, Sedlarikova, Pavel, Pleva, Petr, Filip, Jana, Zelenkova, Alena Opalkova, Siskova

Publikováno v: ACS applied materialsinterfaces. 13(34)

The efficiency of filtration membranes is substantially lowered by bacterial attachments and potential fouling processes, which reduce their durability and lifecycle. The antibacterial and antifouling properties exhibited by the added materials play

Electrospinning represents the very effective process of producing nanofibrous mats. This process is influenced by a number of mutually and strongly interlaced entry parameters (characteristics of polymer, solvent, process parameters) and their parti

Antibacterial electrospun membrane prepared from poly (vinylidene fluoride)-co-hexafluoropropylene with lauric acid monoacylglycerol

Autor: Pavel Pleva, Jana Sedlarikova, Magda Janalíková, Jana Zelenkova, Petra Peer, Petr Filip

Publikováno v: NANOCON Conference Proceedings-International Conference on Nanomaterials

The aim of this study was to prepare an antibacterial nanofibrous membrane using electrospinning technique. The nanofibrous membranes were spun from polymer solution of poly(vinylidne fluoride)-cohexafluoropropylene (PVDF-co-HFP) dissolved in N,N'-di

Approximate functions relating specific viscosity of PEO in DMSO vs. concentration respecting intrinsic viscosity for low concentrations

Autor: Petr Filip, Jana Zelenkova

Publikováno v: Preface: Novel Trends in Rheology VIII.

The plots relating specific viscosity of a solution of poly(ethylene oxide) (PEO) in dimethyl sulfoxide (DMSO) with the corresponding PEO concentration can be seemingly approximated by various functions depending whether the normal, semi-log or log-l

Flexibility of three differential constitutive models evaluated by large amplitude oscillatory shear and Fourier transform rheology

Autor: Jana Zelenkova, Petr Filip, Radek Pivokonsky

Publikováno v: Polymer. 104:171-178

Using Fourier transform rheology the Giesekus, exponential Phan-Tien and Tanner, and modified eXtended Pom-Pom constitutive models were examined in the non-linear regime represented by large amplitude oscillatory shear (LAOS) measurements. For the ex

The role of the Gordon–Schowalter derivative term in the constitutive models—improved flexibility of the modified XPP model

Autor: Petr Filip, Radek Pivokonsky, Jana Zelenkova

Publikováno v: Colloid and Polymer Science. 293:1227-1236

Constitutive models that complete the set of equations describing the flow of polymer melts should respect objective thermodynamics and stability conditions ensuring their validity in the whole range of possible deformation flow. However, in practice
