Role of nano‐size SiO₂ additive on the thermal behavior of cyanoacrylate nanocomposite

Abstract

Nowadays, solvent-free, one-part cyanoacrylate adhesive is widely used in medicine and dentistry. According to a literature survey done by the authors, there are few papers concentrated on the role of nano-sized particles on the thermal behavior of cyanoacrylate glue. Thus the main goal of the current research focused on clarifying the role of nano-sized SiO 2 on the thermal behavior of cyanoacrylate. Thermal behavior of all materials including cyanoacrylate and its nanocomposites was studied by using Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) methods. The results of DSC analysis showed that an increase in the amount of nano-sized SiO 2 results in decreases in the duration of cyanoacrylate curing, energy release during polymerization, and incubation time of polymerization. Furthermore, the results of TGA tests illustrated that the weight loss of cyanoacrylate strongly depends on the contents of both caffeine and SiO 2 . In fact, an increase in nano-sized SiO 2 content increases the degradation temperature of cyanoacrylate.

A facile method of synthesizing size-controlled hollow cyanoacrylate nanoparticles for transparent superhydrophobic/oleophobic surfaces

“…12 Ethyl cyanoacrylate (ECA) is selected as the shell material for the hollow nanoparticles because of its high reactivity and strong adhesive properties. 13,14 This method for fabricating hollow cyanoacrylate nanoparticles (HCNPs) is designated as the supersaturated gascored instant polymerization (SGCIP) method, which uses both the supersaturated gas produced by mixing two solvents and the instant reaction of ECA. The gas-cored polymer structures created via the SGCIP process can predominantly manifest either as a network structure or an assembled particle structure by changing the ratio of the solvents.…”
