Preparation of Electrically Conductive Polystyrene/Carbon Nanofiber Nanocomposite Films

Abstract

A simple and effective approach to prepare conductive polystyrene/carbon nanofiber (PS/CNF) nanocomposite films via a solution dispersion method is presented. Inexpensive CNF, which has a structure similar to multi-walled carbon nanotubes, is chosen as a nanofiller in this experiment to achieve conductivity in PS films. A good dispersion is achieved in the PS matrix with ultrasonication. The experiment to prepare PS/CNF system is suitable as a laboratory experiment for college chemistry or material science course. The experiment provides students with a hands-on laboratory experience in nanotechnology and its related fundamental concept.

“…[1][2][3][4][5][6][7][8][9][10] Among these conductive fi llers, carbon-based materials such as carbon black (CB), [11][12][13] carbon nanotubes (CNTs), [ 5 , 14-21 ] carbon nanofi bers (CNFs), [ 6 , 8 , 10 , 22 ] graphite powder, and graphene nanoplatelets (GnPs), [ 2 , 3 , 7 , 23-26 ] have been used extensively because of their wide availability, low density, high electrical conductivity, and resistance to corrosion. Isotactic poly(propylene) dispersion strategy.…”

“…A wide range of thermoplastics, including poly(propylene) (PP), [9] poly (methyl methacrylate), [10,11] polyethylene, [12] polystyrene, [13][14][15][16] and polycarbonate, [17] have been reinforced with inorganic nanofillers and exhibited improved mechanical performance and electrical conductivity. Isotactic PP, one of the most generally used thermoplastics, has nowadays been widely used in the household appliances, food packaging, automotive, and medical devices, due to its high corrosion and heat resistance, excellent formability and high processability, and low cost.…”

Nanocomposite films and coatings using inorganic nanobuilding blocks (NBB): current applications and future opportunities in the food packaging sector

“…If, on one hand developers have thus far used layered silicates (e.g. clays) the most extensively as llers to obtain nanocomposites, 4,[34][35][36] on the other hand, developers have introduced carbon-based nanollers such as carbon black, [37][38][39] expanded graphite, [40][41][42] carbon nanotubes (CNTs), [43][44][45] and carbon nano-bers [46][47][48] in the preparation of polymer nanocomposites to achieve properties otherwise unattainable, such as electrical and thermal conductivity of the nal nanocomposite material. Among these, CNTs have proven effective as conductive llers.…”
