“…One of the main reasons for ver satility of these fibers in wide range of applications is due to the presence of high thermal stability [12][13][14]. Even though conventional fiber forming process such as wet spinning and dry spinning produces fibers, electrospinning technique has come out as advantage in the hand of the researchers to produce nanofibers.…”

Electrospinning of polymer blends solutions offers the potential to prepare novel nanofibers for use in a variety of applications. Conductive blend nanofibers of polyaniline doped with camphorsulfonic acid (PANi CSA) and polyacrylonitrile (PAN) were prepared by electrospinning process. The influences of PANi CSA content on the morphological, electrical conductivity, and mechanical properties of the blend nanofibers were investigated. The SEM analysis of the nanofibers samples revealed that the average diameter of the nanofibers decreases with increasing PANi CSA concentration. The resultant PAN/PANi CSA blend nanofibers diameters were in the range of 59 to 234 nm. Tensile results showed that 30 wt% PANi CSA load ing to the electrospun PAN/PANi CSA blend nanofibers gave rise to 10 fold and 3 fold increase in the tensile modulus and tenacity of nanofiber layers, respectively. The electrical conductivity measurements of these nanofibers could be adjusted from ~10 -10 S/cm (insulator) to ~10 -1 S/cm (conductor) by choosing the dif ferent amounts of PANi CSA between 0 and 40 wt%. The significant enhanced mechanical and electrical properties of these PAN/PANi CSA blend nanofibers can be utilized for quite promising future electronic applications.

“…PAN fabrics with various excellent properties such as softness, heat retention, a lower density compared to wool, and so on, have been widely applied as substitutes for wool, known as ‘synthetic wool’. However, due to the addition of a third monomer, numerous anionic dyeing sites can be introduced into PAN fibres thus benefitting PAN fibre dyeing but resulting in uneven dyeing . Retardation methods for cationic dyes on PAN fabrics mainly incorporate two aspects: control of the dyeing process and the addition of retarding agents, an effective method .…”

Alkyl imidazole cationic Gemini surfactants (AICGS) with various alkyl chain lengths were used as retarders for dyeing methylene blue (MB) on polyacrylonitrile (PAN) fabrics, with benzyldimethyldodecylammonium chloride (1227) surfactant as a comparison. The exhaustion (E%) of MB on PAN fabrics was investigated at varying surfactant concentrations and dyeing temperatures. Furthermore, kinetic studies on various retarders and 10‐4‐10 AICGS concentrations were carried out. It was found that the retarding dyeing effect of AICGS is stronger when compared with the 1227 surfactant. Moreover, as surfactant concentration increased or the dyeing temperature decreased, E% was reduced drastically. For kinetic studies, the dyeing rate constant increased with an increase in dyeing temperature and a decrease in 10‐4‐10 AICGS concentration, while half‐dyeing time was reversibly decreased.

Box Behnken design of experiment was used to study the effect of process variables such as alkali concentration, temperature and time on water retention capacity of the alkaline hydrolysed electrospun fibres. The hydrolysis of electrospun polyacrylonitrile fibres was carried out using sodium hydroxide with different processing conditions like concentration of alkali, temperature and time. With the increase in the concentration of alkali, time and temperature, the water retention capacity of membrane was found to increase in the membranes. Water retention capacities of the membranes were modeled and predicted using empirical as well as artificial neural network (ANN model). The fiber diameter and mean flow pore diameter of electrospun polyacrylonitrile fibers and hydrolyzed fibers shown in SEM images were 310 AE 50, 275 AE 75 nm, 0.9258 and 1.12 microns, respectively. The present study indicated that the nanofibrous membranes have potential for the water absorbing applications.
