How to shape nanofiber mats.

One of the often used polymers for electrospinning is polyacrylonitrile pan especially for the production of carbon nanofibers but also for a diverse number of other applications. The process developed by asi generates a uniform sheet good with a well developed network of nanofiber supported by the carbon fiber veil that is well dispersed and is durable enough to process on reel to reel processing operations. The photographs c represent the different scaffold that can be created with different mold shapes. This chapter deals with the electrospinning of polyurethane nanofibers and their potential applications.

The nanofiber mats weresoaked intodmem hgmedium for24h. 24 well plates were covered with 1 5 agar to prevent cells to attach onto the surface of culture flask. Schematic illustrating the procedure of converting a 2d nanofiber mat into a cylinder shaped nanofiber scaffold with a a hollow tube shaped mold for a cylindrical shape and b a customized scaffold for a tube shape. A solution of plga nanofibers sprayed from an airbrush forms a mat that conforms to the shape of a surface such as a gloved hand.

For some of these applications e g creation of nano filters the dimensional stability of the nanofiber mats is crucial. To fragment shorten electrospun nanofiber mats membranes a homogenizer such as a high speed blender is commonly adopted while the size of fragmented mats membranes and the length of shortened nanofibers are primarily determined upon the properties of different types of nanofibers and mats membranes as well as the vigorousness and duration of. Each well was plated 1 105 cells well and incubated at 37 cina5 co 2. Shape of the original scaffo lds and had a bone like ap pearance.

A optical and b sem images of nanofiber mat produced via asi s proprietary process. Electrospinning can be used to produce nanofiber mats. The pnipa sax x 3 10 mol nanofiber mats were insoluble in water at 25 c in which inter polymer and inter fiber physical cross links were formed through hydrophobic interaction of stearyl. The nanofibers are put in a petri dish and uv sterilization was done for each side for 2 h.

Nanofiber mat was also used to culture chondrocyte cells. Electrospun pu nanofiber mats exhibiting good mechanical properties may have a wide variety of potential applications in high performance air filters protective textiles wound dressing materials sensors drug delivery etc.
