Recently, nanomaterials are widely preferred from textile manufacturers due to their excellent properties such as high mechanical strength, chemical resistance, water repellence, antibacterial properties etc. Still, a lot of research are carried in this area to improve textile products which already be used. To obtain nano-enhanced textiles, different kinds of processing techniques are needed because existing manufacturing processes are not very suitable. In this case, manufacturing costs, quality control and homogeneity of nanoparticle dispersion through the fabric become problematic issues. Another important issue to be considered for nanoparticle usage is any effects on human health and environment. Although some studies have focused on this issue, still toxicity of nanomaterials in textile product is not fully understood.
In fabric composites, conventional, natural or synthetic fibers are generally mixed with nanomaterials to enhance the performance or create novel properties to the fabric. Some examples of nanomaterials and benefits which can offer to textiles are listed below.
  • Carbon black nanoparticles/nanofibers: electrical conductivity, high mechanical properties and abrasion resistance
  • Carbon Nanotube: Excellent mechanical properties with lightweight, electrical conductivity and thermal conductivity
  • Metal oxide nanoparticles: Antimicrobial properties, photocatalytic, electrically conductive and UV protection
  • Metal nanoparticles: Antimicrobial, Aesthetic properties and solar cells
  • Nanoclay: Fire retardancy, electrical and chemical resistivity, UV shielding
By the help of these nanomaterials, textile products can be used different purposes such as;
  • Antibacterial and odor-reduced sports fabrics with improved mechanical properties
  • Personal protective textiles with enhanced chemical, heat resistance and durable.
  • For military purposes, flexible body armor, radio shielding and ballistic protection.
  • Medical textiles with antimicrobial wound dressing and bedding
  • Wearable electronics with conducting fabrics

Improving Dialysis Process with Graphene

Researchers from Mechanical and Electrical Engineering Departments of MIT recently showed that graphene is a powerful material candidate for use in the dialysis systems (such as hemodialysis machines in medical institutes for filtering human blood). In order to prepare graphene as a dialysis material, researchers used a procedure opposite to the general treatments that nanotechnology people use. Dialysis is a process of filtering different solutions such as human blood by a membrane in order to remove waste molecules, drugs, chemical residues from the solution. In some cases, the process can be used for purification of chemicals or isolation of different molecules for medical diagnosis. It is an essential process for scientists especially in the medical operations.

Graphene Oxide Dispersion

Graphene oxide refers to a mono-atomic layer material obtained when graphite crystals are oxidized. This is one of the graphene materials that are commercially available because of  its ability to dissolve in water  which makes the oxidation process suitable. In this article, we will talk about the  synthesis, the properties and some of the applications of graphene oxide dispersion in water . Seven Properties of Graphene Oxide Dispersion The properties of a material are defined through its structure, however, this material is very peculiar, since there is no unambiguous model of this material. Graphene Oxide dispersion offers remarkable physical, chemical and mechanical properties that give the opportunity to new applications. Graphene Oxide is amorphous , but, in general, graphene oxide can be described as a two-dimensional sheet containing honeycomb carbon atoms with functional groups of hydroxide and oxygen, unlike the graphene model that seeks to completely re...
