Surface-modified graphite nanomaterials for improved reinforcement efficiency in cementitious paste

Cup‐Stacked Carbon Nanotube Schottky Diodes for Photovoltaics and Photodetectors

“…[ 43 ] CSCNTs electronics have been poorly studied [ 44,45 ] because of a higher interest in composite materials applications. [46][47][48] However, unlike 1D-carbon nanostructures such as MWCNTs or graphitic fi bers, CS-CNTs have been found to exhibit an energy band gap. [ 44 ] The optical transitions observed in such semiconducting quasi-1D nanostructures were found to be responsible for charge separation and enabled charge harvesting for generating photocurrent in a photo-electrochemical cell with a maximum effi ciency value much larger than those obtained for SWCNT electrodes.…”

Evaluation of modified-graphite nanomaterials in concrete nanocomposite based on packing density principles

“…For this purpose, CNFs were dispersed in water in the presence of a polymer (PAA) at a polymer-to-CNF weight ratio of 0.1:1.0 [27]. CNFs were mixed with PAA in 30% of concrete mixing water and sonicated for 30 min.…”

Optimization of ultra-high-performance concrete with nano- and micro-scale reinforcement

“…PAA carries a high density of COOH groups, wrapping of CNFs with PAA to improve dispersion of CNFs in water, and their bonding with cement hydrates. For the purpose of modifying CNFs with PAA, CNFs were dispersed in water in the presence of PAA at PAA:CNF weight ratio of 0.1:1.0 (Peyvandi, Soroushian, Abdol, & Balachandra, 2013).…”
