“…Using the mass after solvent desorption as the starting mass, the purified SWCNT show a weight loss of 5% following thermal desorption to 700°C. This result is consistent with other reports of thermal desorption measurements performed on purified SWCNT materials, which show weight losses in the range of 5-20% under similar conditions [19][20][21][22][23]. This suggests that there are low levels of adsorbates and/or functional groups present on the nanotubes after only the synthesis and purification steps, which is also consistent with observations made by other groups [7,11].…”

“…Exercising control over the oxidizing conditions affords some ability to differentiate between sample components [18]. More recently, TG has been applied under inert desorption conditions to monitor adsorbates and functional addends attached to CNT samples [19][20][21][22][23]. In the majority of such cases, it is assumed that the total loss in sample mass can be attributed entirely to the liberation of the specific functional moieties being studied, which then allows the estimation of the degree of functionalization.…”

SummaryOne of the main issues in the production of polymer nanocomposites is the dispersion state of filler as multilayered graphene (MLG) and carbon nanotubes (CNTs) tend to agglomerate due to van der Waals forces. The agglomeration can be avoided by using organic solvents, selecting suitable dispersion and production methods, and functionalizing the fillers. Another proposed method is the use of hybrid fillers as synergistic effects can cause an improvement in the dispersion state of the fillers. In this review article, various aspects of each process that can help avoid filler agglomeration and improve dispersion state are discussed in detail. This review article would be helpful for both current and prospective researchers in the field of MLG- and CNT-based polymer nanocomposites to achieve maximum enhancement in mechanical, thermal, and electrical properties of produced polymer nanocomposites.

“…% CB show 19% and 23% higher modulus than neat epoxy, respectively. Good interfacial bonding between carbon black fillers and epoxy matrix has been shown to transmit stress from the matrix to the filler, and further promotes the enhancement of flexural property of epoxy composites (Yang et al, 2009;Nayak et al, 2007;Khalil et al, 2010).…”

In the present work, epoxy/carbon black (CB) composites were made with 1, 2, 3, 4 and 5 wt. % of CB. The tensile test, flexural test, and impact test of the epoxy/CB composites and neat epoxy were performed and, their results were compared. The results conclude that the tensile strength, flexural strength, and impact strength of the 4 wt. % of CB composites is better than the other composites and neat epoxy. Thermal graphic analysis (TGA) and differential scanning calorimeter (DSC) of the pure epoxy and composites were calculated and analyzed. The results found that the glass transition (Tg) of the neat epoxy was increased with the addition of CB content up to 4 wt. % and then it was decreased. The decomposition temperature of the composites was increased with the increased in the CB content.
