“…This range can be termed as the processing window or optimum range beyond which electrospinning is not possible. Many applications of electrospun fibers and membranes include biomedical (tissue engineering [12][13][14], drug delivery [15][16][17], immobilization of enzymes [18][19][20], wound dressing [21][22][23] and antibacterial membranes [24][25][26]), textiles [27][28][29], separation membranes (Li ion battery separators [30][31][32], distillation [33][34][35] and filtration membranes [36][37][38]), sensors [39][40][41], and high performance composite materials (reinforcing agents [42][43][44] or vascular networks of healing agents [45][46][47]), etc.…”

Electrospinning is a versatile technique which results in the formation of a fine web of fibers. The mechanical properties of electrospun fibers depend on the choice of solution constituents, processing parameters, environmental conditions, and collector design. Once electrospun, the fibrous web has little mechanical integrity and needs post fabrication treatments for enhancing its mechanical properties. The treatment strategies include both the chemical and physical techniques. The effect of these post fabrication treatments on the properties of electrospun membranes can be assessed through either conducting tests on extracted single fiber specimens or macro scale testing on membrane specimens. The latter scenario is more common in the literature due to its simplicity and low cost. In this review, a detailed literature survey of post fabrication strength enhancement strategies adopted for electrospun membranes has been presented. For optimum effect, enhancement strategies have to be implemented without significant loss to fiber morphology even though fiber diameters, porosity, and pore tortuosity are usually affected. A discussion of these treatments on fiber crystallinity, diameters, and mechanical properties has also been produced. The choice of a particular post fabrication strength enhancement strategy is dictated by the application area intended for the membrane system and permissible changes to the initial fibrous morphology.

“…The latent heat of these fibers is 88.0.71 J/g, which is better than some functional fibers. 33,47 After thermal cycling treatment, the T m and 4H m decreased by 1.79 C and 2.06 J/g, respectively, without significant changes. Through the comparison of fiber properties before and after thermal cycling, it can be concluded that PVDF-NaCl@CBT-V 0.4 possesses Feed rate (ml/h) excellent thermal stability and reliability.…”

“…Adding some functional materials into the fibers can respond to external stimuli, such as, light, heat, electric, and magnetic fields, making these materials have applications in monitoring, control, and sensing. [32][33][34][35] Phase change thermochromic materials have received widespread attention due to their heatsensitive reversible color and temperature regulation characteristics. The Japanese Dream Company has produced color-changing octopus toys, which are deeply loved by children.…”

Recent years, phase change materials (PCMs) with potential to store and transform energy have attracted broad attention, especially in the field of thermal energy storage. However, the instability and leak proneness of PCMs limit their universal application. In this paper, core-shell fibers with 1-tetradecanol (TD) as core and poly(vinylidene fluoride) (PVDF) as shell were prepared via melt coaxial electrospinning method, and for improvement, the dye composed of crystal violet lactone (CVL) and bisphenol A (BPA) was added to the core to endow the fiber the function of reversible thermochromism. During the preparation process, it was found that the addition of NaCl could regulate the fiber morphology and strength its mechanical property. By adjusting the concentration of shell solution and the flow rate of core solution, the high-strength reversible thermochromic fibers were produced when polymer concentration was 24 wt% with a core feed rate of 0.4 ml/h. The latent heat of these fibers is up to 88.71 J/g. Besides, its color can change from blue to white when heated, and the transition temperature is around 38 C. And 100 thermal cycle tests of the fiber showed its strong thermal stability and thermochromic property.

“…Several methods to coat graphene on cotton fibers were recently developed. For example, Ag and Cu nanoparticles were incorporated into reduced GO (RGO), and cotton fabrics were successfully coated with modified RGO nanoparticles using 3-glycidyloxypropyl trimethoxy silane as a coupling agent [ 35 , 36 , 37 , 38 , 39 , 40 ]. However, this approach requires the chemical modification of the graphite nanoparticles with metals through the use of solvents or chemical coupling agents.…”

Transport Properties of Natural and Artificial Smart Fabrics Impregnated by Graphite Nanomaterial Stacks

In this work, we studied the transport properties (thermal and electrical conductivity) of smart fabric materials treated with graphite nanomaterial stacks–acetone suspensions. An innovative and easy method to produce graphite nanomaterial stacks–acetone-based formulations, starting from a low-cost expandable graphite, is proposed. An original, economical, fast, and easy method to increase the thermal and electrical conductivity of textile materials was also employed for the first time. The proposed method allows the impregnation of smart fabric materials, avoiding pre-coating of the fibers, thus reducing costs and processing time, while obtaining a great increase in the transport properties. Two kinds of textiles, cotton and Lycra®, were selected as they represent the most used natural and artificial fabrics, respectively. The impact of the dimensions of the produced graphite nanomaterial stacks–acetone-based suspensions on both the uniformity of the treatment and the transport properties of the selected textile materials was accurately evaluated using several experimental techniques. An empirical relationship between the two transport properties was also successfully identified. Finally, several theoretical models were applied to predict the transport properties of the developed smart fabric materials, evidencing a good agreement with the experimental data.
