Climate controlled electrospinning. What about those shoelaces you always use to tie your shoes? Imagine them in millions of smaller versions. Do you think? So now you know something about nanofibers :)) Materials called nanofibers are made up of threads so thin that their thickness can be expressed in nanometers. It has different areas of application. With the nanofiber method, for example, the surface can be increased enormously, depending on the material used, either a selectively permeable membrane or a superhydrophobic surface.

Electrospinning of nanofibers and their applications for energy devices

This is a definition that anyone can understand, but not enough for those who want details. Those who want to get detailed information in this field (about nanofiber production and its production method, electrospinning method, HEPA filter nanofiber membrane, textile soundproofing materials with antibacterial performance, etc.) can get it from spingenix.com, The first and only . A group that does it industrially in Turkey.

Climate Controlled Electrospinning

Nanofibers, nanofibers, are fine fibers with mean fiber diameters in the nanometer range (nm = 9-10 m), which correspond to about one-thousandth of a human hair. For fibers in general, the term “nano” provides information about the diameter size of the fibers. Today, “fibers one micron in diameter and smaller” are called nanofibers because fibers one micron in diameter or smaller cannot be produced with current fiber manufacturing processes. One of the newest technologies developed for the production of these fibers is the process of electrical manufacture (electrospinning). In general, many applications show that the nanofibers under investigation will soon find their way into many areas of life. The electrospinning process is the most efficient and simplest method to produce polymer-based nanofibers. It is also possible to produce nanofibers using special spinning processes and gas vapor growth processes.

They are fibers less than a micron in diameter that, unlike normal fibers, cannot be seen individually with the naked eye and can be manufactured in a porous paper-like membrane structure. Membrane structures made from nanofibers have unlimited uses with various mechanical and chemical modifications. Air and liquid filters, medical and energy applications, high-performance fabrics are just a few of them. Although there are many methods for its production, the most suitable and widespread marketing method is electrospinning. Although the price per kilo varies depending on the application, it is around 20,000 tomans, but the production costs are incomparably lower than this price. Measured as it is, we will encounter it in many areas in the future. The production of nanofibers by electrospinning is still being studied at almost all universities in our country.

Electrospinning Environment

Nanofibers are fibers as thin as a thousandth of a human hair. Areas of application are medical textiles, bandages, outerwear. Among the methods for obtaining nanofibers, electrospinning is distinguished by its simple and inexpensive structure and short processing time. While the fabrication of nanofibers from synthetic materials by electrospinning is widespread, interest in the fabrication of nanofibers based on biopolymers has increased in recent years. For this reason, the rheological and conductivity properties of chickpea flour, lentil flour, soy protein and hydroxypropylmethylcellulose (HPMC) solutions prepared in different concentrations were first measured. Then, the prepared solutions were subjected to electrospinning under various conditions.

Optimal solution concentration and electrospinning parameters were determined considering the homogeneity of the nanofibers. Electrospun nanofibers are an advantageous option for active packaging due to their high surface-to-volume ratio. His goal in this project is to reduce the oxidation rate of food through active packaging with antioxidants. To this end, different ratios of gallic acid were successfully encapsulated in chickpea flour, lentil flour, soy protein, and hydroxypropylmethylcellulose-based nanofibers by electrospinning methods. The gallic acid loading efficiency and antioxidant capacity of the obtained homogeneous nanofibers were determined, and nanofibers with high efficiency and high antioxidant content were used for packaging nuts. As a result of the rapid oxidation test, it was found that the nuts packed with nanofibers containing gallic acid had a lower oxidation value than the nuts in the control group. Therefore, the preparation of gallic acid-containing nanofibers based on biopolymers was successfully carried out and the use of the obtained nanofibers as an active packaging material was proposed.
