The development of nanocellulose from cellulose which was discovered more than 100 years ago, is a landmark in the field of pharmaceuticals, chemical, paper, automobile, electrical, oil, and ink industries. Nanocellulose is an ideal excipient as it is cheap, biodegradable, biocompatible, and easy to synthesize and scale-up. It is a versatile excipient which can be exploited in a variety of applications in medicine and nonmedical applications. Nanofibers can be used in drug delivery systems, advanced wound management, medical devices, etc. Many pharmaceutical formulations based on nanocellulose are already in the market, and numerous formulations are under development and clinical trials. We can conclude that nanocellulose is the excipient of the future owing to its unique physicochemical properties and versatility.

For this reason, nanofibers have become the major interest of researchers because of their desirable properties for filtration, such as mechanical strength, elasticity porosity charged surface area, among others [51]. In contrast to the micro-sized fibers with an average diameter from several to tens of micrometers, the nanofibrous air filters with an average diameter below 1.0 gm exhibit higher removal efficiency toward ultrafine PM [26].

The electrospinning technique allows for producing nanofibers with several applications. It is the most recent technique in the food industry in the area of packaging for the production of innovative materials with improved properties (Wang et al., 2011; Moreira et al., 2018a). Nanofibers for food packaging applications present structural advantages, in addition to high mechanical resistance (Shen et al., 2011).

Nanofibers are potential used for filtration with high filtration efficiency. High specific surface area of nanofibers could also yield filtration efficiency. CNTs (Md. Harun-Or & Stephen, 2017) and silk nanofibers (Zhou et al., 2015) have been investigated for their potential use in filtration application. Currently, CNTs based nanofibers are difficultly fabricated for filtration application. Silk, natural protein fiber, is edible, environmental sustainable, and widely available (Wang et al., 2016). Regenerated silk fibroin (SF) nanofibers can be easily fabricated by electrospinning. In this work, we explore the application of SF based nanofibers in the field of filtration. CNTs are added to SF solution with different concentration to form spinning solution. A series of SF-CNTs nanofibers are fabricated by electrospinning, and compounded with polypropylene (PP) non-woven fabric.

Nanomaterials can be categorized to be materials in the size range between 1 nanometer and 1000 nanometers, in at least one dimension [1]. Due to the large surface-to-volume ratio, the nanomaterials have the capability of offering unique properties including the following: (a) good mechanical properties, (b) low load-carrying capability and (c) other properties that are specific and relevant to their selection and use for an application. Nanomaterials, such as: (i) carbon nanotubes [23456789101112131415], (ii) carbon nanofibers [16171819202122232425], (iii) graphene [26272829303132333435363738] and (iv) montmorillonite (MMT) [39404142], have – in the time period spanning the last three decades – engendered increased attention and action by way of research carefully and comprehensively conducted by a sizeable number of researchers. In fact, nanofibers are now being considered as an important nanomaterial that is gaining increased attention and acceptance for use in a spectrum of industry-related applications.

Polymeric nanofibrous mats are an important class of nanomaterials and have wide applications in the nanotechnology field. Nanofibers have a diameter in the range of nanometer (less than 100 nm). They possess various physical properties and a wide range of applications [7]. Many natural and synthetic polymers like cellulose, chitosan, alginate, keratin and polycaprolactone, polyurethane and polylactic acid respectively are used to fabricate nanofibers [8]. The diameter can be varied by changing the method of production and type of polymers. Fabricated nanofibers have unique properties like high surface to volume ratio, high porosity and good mechanical properties [9, 10].
