Opis:
In order to improve the pore size of the polycapro-lactone (PCL) and polycaprolactone/hydroxyapatite (PCL/HAp) nanofibrous scaffolds, salt-leaching technique together with electrospinning method were applied. Salt particles were incorporated within the polymer nanofibrous matrix and then were leached out to generate some macropores. Microstructure, pore size distribution and average fibre diameter of the scaffold were investigated by scanning electron microscopy and PMI capillary flow porometer. Mechanical properties were determined by means of tensile test. Presence of hydroxyapatite and chemical characterization of the scaffold were done by FTIR analysis.

Opis:
Electrospinning is a simple and universal way to produce fibres from a variety of materials having diameters ranging from submicrometers to nanometers. Such fibres can be formed from resorbable and non-resorbable polymers, ceramics and their different combinations containing nanoparticles. Such a method has gained a great interest in medicine due to its ability to form a fibrous space architecture, similar to the natural extracellular matrix [1,2]. On the other hand, due to a wide range of technical facilities of electrospun fibers the method allows to create directionally-dependent space architecture of nanofibres which mimic natural tissues [3]. Considering the similarities between the microstructure created by nanofibres and the extracellular matrix, nanofibrous materials made by ES technique seem to be promising scaffolds to regenerate cartilage [4] and neural tissue [5]. A material which is used for cartilage scaffolds should mimic native cartilage, which is known to have an oriented structure associated with its mechanical and physiological functions [5]. Scaffold with a biomimetic-oriented architecture is an important requirement for tissue-engineered cartilage. In this study, PLA oriented and non-oriented fibrous scaffolds were manufactured. Selected properties of the materials were analysed and dissussed in view of the manufacture of optimal structure for cartilage tissue engineering.

Opis:
The process of production of filtration mats of various thickness from PVC and PVDF polymers by the electrospinning method is presented in the paper. Filtration of nanoparticles and submicron particles is an important problem in industry and health protection systems, in particular in air-conditioning and ventilation appliances. This problem can be effectively solved by application of non-woven fibrous filtration mats. The experimental investigations of mechanical properties of nanofibrous filtration mats produced by electrospinning and the measurements of removal efficiency of submicron particles from flowing gas have indicated potential usefulness of these nanomats for gas cleaning of air-conditioning systems and/or ventilation ducts. The experimental results obtained for cigarette smoke of a mass median diameter of about 1 μm, used as test particles, have shown that nonwoven nanofibrous filtration mats produced by electrospinning have a good filtration efficiency for nano- and submicron particles, owing to a pressure drop similar to HEPA filters. Particles of this size are particularly difficult to be removed from the flow by a conventional method, for example, by a cyclone or electrostatic precipitator.

Opis:
Novel polyurethanes based on synthetic, atactic poly[(R, S)-3-hydroxybutyrate] (a-PHB) and polycaprolactone (PCL) or polyoxytetramethylene (PTMG) diols were synthesized. It was shown that the presence of a-PHB within soft segments reduces crystallinity of PUR. Because of the low melting temperature for polyurethanes with PCL in soft segments, at this stage of work, electrospinning was limited to polyurethanes containing PTMG and a-PHB. Polyurethane containing 80% of PTMG and 20% of a-PHB was electrospun at various parameters from hexafluoro-2-propanole solution, resulting in formation of fibers with the average diameter ca. 2 μm. The fiber diameter decreased with decreasing polymer concentration in a solution and was practically insensitive to the needle-collector distance in the applied range of distances.

Opis:
Present nanofiber technology is one of the most important objects in the recent research topics. Electrospinning is a unique technology that can produce non-woven fibrous materials with interesting characteristics such as diameters ranging from sub-micron to several nanometers, high surface to volume ratio, high porosity and small interfibrous pore size. Polymer nanofibres have great potential for technical applications in filtration, composites and electronics. Nanofibers are also of importance in many different applications as the drug delivery, biomaterials and tissue engineering. For these applications there is a great need for polymer nanofibers with well defined surface properties. In this field, plasma surface treatment has been applied in the textile industry for the modification of polymer nanofibers. In this study, chitosan nanofibers were prepared by modified electrospinning method called NanospiderTM and treated with plasma in the presence of methane gas. The surface characteristics of the nanofibers after plasma treatment were examined using contact angle measurements, SEM and XPS analysis.
