Nanofiber Production with Other Techniques

Generally, fibers can be defined as objects or materials that have an elongated structure, as shown in Fig. 1.1. There are other definitions according to the field they are used in, such as the textile industry, biochemistry, botany, physiology, and anatomy. With regard to fibers, nano refers to the diameter of the fiber. However, libers as less than 1 pm are accepted as nanolibers. In the industiy, it is acceptable to classify fibers up to 500 nm as nano, whereas some scientists use the term submicron.  

Nanofibers present a high surface-area-to-volume ratio, better mechanical properties, for example, good directional strength, and flexibility, so they can be utilized for a wide variety of materials and applications, including for their mechanical, biomedical, optical, electronical, and chemical properties. 

A comparison between different techniques is given in Table 1.1. Among all, electrospinning is the best candidate for further development, with a wide range of opportunities to be utilized in all types of polymers (l oth S3mthetic and natural] and ceramics. 

Drawing It requires simple equipment. No continuous fibers, no control on fiber dimension 

Ibmplate Synthesis Fibers of different diameters can be obtained by using different templates. Process not easily scaled up
