“…In light of the challenges faced in the testing of individual nanofiber, it would be desirable to develop a quantitative relationship between the tensile properties of an individual nanofiber and a nanofiber membrane. Therefore, the tensile properties of random nanofiber membranes, which are easily obtained from macroscopic tensile tests of the membrane, can be used as an indicator of the mechanical properties of individual nanofiber [ 25 , 26 ]. Computer modeling of electrospun nanofiber membranes is a difficult task, because of the randomness of the meso structure of the fiber web and its sophisticated mechanical response.…”

The mechanical properties of electrospun nanofiber membranes are critical for their applications. A clear understanding of the mechanical properties that result from the characteristics of the individual fiber and membrane microstructure is vital in the design of fiber composites. In this reported study, silk fibroin (SF)/polycaprolactone (PCL) composite nanofiber membranes were preparedusing an electrostatic spinning technology. The nanofiber orientation distribution (FOD) of the membrane was analyzed using multi-layer image fusion technology, and the results indicated the presence of an approximately uniform distribution of fibers in the electrospun membranes. The relationship between the single nanofiber and the membrane was established by analyzing the geometrical structure of the cell by employing a representative volume element (RVE) analysis method. The mechanical properties of the 272 nm diameter SF/PCL composite fibers were then predicted using the developed model.

“…Such effect is widely known in literature for all polymer solutions (16). Lower solution viscosity, in turn, leads to the formation of thinner fibers, as stated elsewhere in literature (17,18). For the thinning of the fibers the increased conductivity of the solution may also be responsible.…”

In this work, three different methods of preparation of polyacrylonitrille (PAN) with carbon black (CB) solutions further used in electrospinning for producing conductive fiber mats are discussed. CB is used as conductive filler. Content of CB in polymer matrix is varied, CB/PAN D 1/2, 1/1, and 3/2. The solution properties and obtained fiber morphology are analyzed. The effect of preparation on fiber morphology and conductivity is analyzed, as well as the effect of sonication on solution properties, morphology, and conductivity of PANCCB samples.

The main focus of this study is to investigate the influence of functional groups of cellulose and its derivatives on properties and morphology of alumina materials obtained by template synthesis. Cyanoethyl-, amidoethyl-and carboxymethylcellulose were synthesized from bleached softwood pulp and they were used as templates for alumina materials preparation. By means of methods of scanning electron microscopy and nitrogen physical sorption it was shown that properties and type of functional groups of template can influence on the morphology and textural characteristics of obtained ceramic materials. The alumina specimens that obtained from cyanoethyl-, amidoethylcellulose have thicker fibers and two times increased surface area in comparison with alumina obtained from initial cellulose but the one formed by carboxymethylcellulose have thin alumina fibers and three times decreased surface area. Thus, by regulating properties and type of template it is possible to obtain ceramic materials with desired properties and morphology.
