Carbon nanotube/polyurethane films with high transparency, low sheet resistance and strong adhesion for antistatic application

Abstract

Carbon nanotube/poly(urethane) films for antistatic application with high transparency, low sheet resistance and strong adhesion were obtained by optimizing the ratio of SWCNT to WPU.

Mechanism of surface treatments on carbon nanotube transparent conductive films by three different reagents

“…Moreover, the lowest sheet resistance was found for the CNT-TCFs treated with HNO 3 solution, which is consistent with a previous report. 17 As TCFs were placed in the HNO 3 solution, the CNTs in the CNT-TCFs may undergo chemical oxidation during post-treatment by attachment of functional groups such as carboxyl groups. From this we believe that the H + in HNO 3 , that is the strong acidity, causes the non-conductive SDBS to be removed from the surface of the CNTs.…”

“…There are several post-processing methods for improving the conductivity of the CNT-TCFs without affecting the transmittance, such as immersion in HNO 3 , H 2 SO 4 or SOCl 2 , and ptype and n-type doping of the CNTs. [17][18][19][20][21] Compared to these methods, a very effective treatment of using HNO 3 is suggested. The purpose of this treatment is to remove the surfactants used for dispersing CNTs in solution and create a denser CNT lm.…”

Effect of Carbon Nanotubes (CNT) Functionalization and Maleic Anhydride-Grafted Poly(trimethylene terephthalate) (PTT-g-MA) on the Preparation of Antistatic Packages of PTT/CNT Nanocomposites

“…However, in the production of antistatic packaging for storage and transport of electronic components and devices, the insulating characteristic of the most polymers can result in electrostatic tensions accumulation, which, if not dissipated, can generate electrostatic discharge (ESD) capable of damaging and invalidating the product [1,2]. Many studies associate several polymers such as polyvinyl chloride (PVC) [3], low-density polyethylene (LDPE) [4], polyurethane (PU) [5], poly(lactic acid) (PLA) [6], polyamide 6/linear low-density polyethylene blends (PA6/LLDPE) [7], and aromatic polyesters such as poly(ethylene terephthalate) (PET) [8,9] and poly(trimethylene terephthalate)/acrylonitrile butadiene styrene blends (PTT/ABS) [10] as excellent candidates for the preparation of antistatic packaging.…”

Experimental study of improved rheology and lubricity of drilling fluids enhanced with nano-particles

“…Other important studies on nano-particle (e.g. graphene oxide, carbon nanotubes etc) influence on solubility, mechanical properties and adhesion include Lvov et al (2011), Jin et al (2014) and Tian et al (2017). The current study is restricted for brevity to the laboratory analysis of only two nano-particles.…”
