There is an urgent need to develop novel antimicrobial cotton textiles (CT) because microbial contamination is one of the greatest threats to public health due to the emerging of infectious diseases and drug-resistant pathogens. In this work, an isocyanate group containing borneol-based antimicrobial finishing agent (NCO-B) was developed which can be covalently grafted to the surface of cotton textiles by a simple one-step method. The obtained NCO-B-finished CT (NCO-B-CT) exhibited broad-spectrum antimicrobial adhesion properties against bacteria (E. coli), including superbugs (MRSA), and fungi (A. niger). Due to its unique antimicrobial mechanism of borneol stereochemistry, the obtained NCO-B-CT is a non-releasing antimicrobial material which causes no skin sensitization and has no cytotoxicity. The mechanical properties of the CT were also improved after this finishing process. Additionally, it displayed durable washing fastness and antimicrobial properties by bearing 50 times laundering cycles. Therefore, this material may have great potential for application in multifunctional textiles, flexible skin electronics and medical protection.

“…In addition, current nanotechnology in the chemistry and biophysics fields has undergone a remarkable development through the "discovery of the nanosized architecture" such as carbon nanotubes [44], "their deployment to the nanocomposite materials [45][46][47][48]", and "re-attention to the bottom-up technologies as the classical LB method [1]". Performance enhancement of analytical techniques, such as scanning probe microscopy and X-ray diffraction, has also helped strongly to the development of nanoscience.…”

In this chapter, a study on two kinds of examples of functional nanofibers has been introduced. In the first section, the formation of nanofiber morphology at a mesoscopic scale and molecular level stacking of a tetrathiafulvalene (TTF) derivative with a chiral group were investigated by the one-dimensional growth method in interfacial molecular films. Monomolecular films of a TTF derivative with a chiral borneol group display a two-dimensional phase transition at the air/water interface. The formation of nanonetwork domains is attributed to the organized aggregation of the TTF derivatives, which is a result of strong intermolecular interactions. In the second section, the formation of nanofiber morphology at a mesoscopic scale and molecular level packing of an amphiphilic diamide derivative with two hydrocarbons were investigated by the in interfacial molecular films. It has found that the growth of this nanofiber morphology is encouraged by the application of the epitaxial growth in the spin-cast film with 1 wt% layered silicate having long hydrocarbons. As mention above, it is found that mesoscopic morphological formation of super-hierarchical structure of the nanofibers having a crystalline arrangement at Å level can be induced conductivity and the thixotropy at macroscopic level.
