“…Therefore, the dispersing abilities of the as-prepared PTU dispersant were investigated. As reported in previous studies, the greater absorbance represented the better dispersion performance because the scale of absorbance is related to the number of particles contained in the unit volume of the dispersion . The dispersion of MWCNTs at varied dispersant concentrations was characterized using UV–vis spectroscopy by recording the absorbance values at 200–800 nm (Figure ).…”

“…Wang et al 9 directly functionalized SWCNTs with tannic acid (TA) through the π−π interactions between the aromatic rings of TA and graphene structures of CNTs. As a kind of eco-friendly and cheap biomass resource, 13,14 TA exhibits a high affinity toward various organic and inorganic substrates due to inherent abundant phenolic hydroxyl groups. 15−17 Inspired by the work of Wang, we proposed that poly(tannin urethane) (PTU) should exhibit superior dispersing ability of MWCNTs by step polymerization between biomass TA and toluene diisocyanate (TDI).…”

The individually dispersed multiwalled carbon nanotubes (MWCNTs) enable the comprehensive accomplishment of intrinsic electrical conductivity, thermal conductivity, and antielectromagnetic shielding characteristics. However, the design of an aqueous carbon nanotube (CNT) dispersant remains a significant challenge in rational balances of strong interfacial interactions between CNT/dispersant and water medium. In the current research, biomass tannic acid (TA) was selected as the building block to synthesize poly(tannin urethane) (PTU) by step polymerization of TA and toluene diisocyanate, which was examined as a novel dispersant for MWCNTs. A highly homogeneous dispersion of PTU-stabilized MWCNTs and carbon black (CB) was prepared by a simple sonification and homogenization process to form aqueous antistatic additives. Furthermore, the antistatic coating for a flexible poly(vinyl chloride) (PVC) substrate was prepared by a dip-coating method using self-made waterborne polyurethane (WPU) as a binder. The results demonstrated that the aggregates of MWCNTs were successfully debundled into individually dispersed nanotubes by taking advantage of the high π−π interaction between MWCNTs and PTU. Compared with the chemical modification, the physically stabilized MWCNTs displayed fewer defects (I D /I G ∼ 0.853). Compared with the pure WPU coating, the sheet resistivity of the MWCNTs/CB/PTU/WPU coating decreased sharply from 10 16 to 10 8 Ω at 0.5 wt % loading of MWCNTs, which met the requirement of antistatic applications. With further increase of the MWCNT content, the MWCNTs/CB/PTU/WPU coatings exhibited continually decreasing sheet resistivity and reached remarkably low surface resistance of 10 4 Ω at 2.0 wt % loading of MWCNTs, which was realized by the formation of conducting networks of synergistic MWCNTs and CB-induced low percolation threshold. The facile one-pot preparation of biobased PTU and simple production of MWCNT dispersion promise an ideal additive for antistatic and conductive-related applications, especially for flexible substrates.

“…Si, Shuxian et al suggest a novel and effective technique for non-covalent modification of carbon nanotubes (CNTs) based on mussel-inspired polymerization of tannic acid (TA) and triethylenetetramine (TETA), followed by surface-initiated atom transfer radical polymerization (SI-ATRP). Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and photography were used to investigate the successful preparation of polymer brush grafted CNT (CNT-P(TA-TETA)-PDMAEMA) composite as well as the pH-responsive behavior of the composite [89].…”

Nanotechnology has undergone significant development in recent years, particularly in the fabrication of sensors with a wide range of applications. The backbone of nanotechnology is nanostructures, which are determined on a nanoscale. Nanoparticles are abundant throughout the universe and are thought to be essential building components in the process of planet creation. Nanotechnology is generally concerned with structures that are between 1 and 100 nm in at least one dimension and involves the production of materials or electronics that are that small. Carbon nanotubes (CNTs) are carbon-based nanomaterials that have the structure of tubes. Carbon nanotubes are often referred to as the kings of nanomaterials. The diameter of carbon is determined in nanometers. They are formed from graphite sheets and are available in a variety of colors. Carbon nanotubes have a number of characteristics, including high flexibility, good thermal conductivity, low density, and chemical stability. Carbon nanotubes have played an important part in nanotechnology, semiconductors, optical and other branches of materials engineering owing to their remarkable features. Several of the applications addressed in this review have already been developed and used to benefit people worldwide. CNTs have been discussed in several domains, including industry, construction, adsorption, sensors, silicon chips, water purifiers, and biomedical uses, to show many treatments such as injecting CNTs into kidney cancers in rats, drug delivery, and directing a near-infrared laser at the cancers. With the orderly development of research in this field, additional therapeutic modalities will be identified, mainly for dispersion and densification techniques and targeted drug delivery systems for managing and curing posterior cortical atrophy. This review discusses the characteristics of carbon nanotubes as well as therapeutic applications such as medical diagnostics and drug delivery.

Degradable Polymer Stars Based on Tannic Acid Cores by ATRP

et al. 2019

Degradable polymers are crucial in order to reduce plastic environmental pollution and waste accumulation. In this paper, a natural product, tannic acid was modified to be used as a polymer star core. The tannic acid was modified with atom transfer radical polymerization (ATRP) initiators and characterized by 1H NMR, FT-IR, and XPS. Twenty-five arm polymer stars were prepared by photoinduced ATRP of poly(methyl methacrylate) (PMMA) or poly(oligo(ethylene oxide) methacrylate) (molar mass Mw = 300 g/mol) (P(OEO300MA)). The polymer stars were degraded by cleaving the polymer star arms attached to the core by phenolic esters under mild basic conditions. The stars were analyzed before and after degradation by gel permeation chromatography (GPC). Cytotoxicity assays were performed on the P(OEO300MA) stars and corresponding degraded polymers, and were found to be nontoxic at the concentrations tested.
