“…They are easily degraded on contact with water (52,53) and basic solutions (54), at elevated temperature (55)(56)(57), and in solvents such as acetone, acetonitrile, and dichloromethane (58,59). This is generally recognized as one of the major disadvantages of cyanoacrylate adhesives, and such poor performance can be attributed to the ease of degradation that occurs when the polymer is exposed to elevated temperatures or moisture, or even on contact with various solvents.…”

Alkyl 2‐cyanoacrylate monomers are commonly used as instant adhesives or “superglue,” mainly because of their unique ability to undergo rapid polymerization under ambient conditions on a wide range of surfaces. This article overviews the chemistry and physical properties of these materials, the most common methods of preparation, their mode(s) of polymerization, and typical performance properties. The main performance limitations of alkyl 2‐cyanoacrylate adhesives, such as poor hot strength and resistance to extreme environments (high heat and humidity) are explained in terms of the susceptibility of the polymer to degradation, and how the chemical structure of the polymer directly affects this degradation process. An overview is given of how the performance properties of cyanoacrylate adhesives are modified through the inclusion of various thickeners for viscosity modification, accelerators for cure acceleration, and recent advances in two component cyanoacrylate adhesives. The uses of polycyanoacrylates in medical adhesive applications and for the preparation of nanoparticles for drug delivery are briefly reviewed.

An experimental assembly has been constructed to measure the specific heat capacity of macroscopic graphite samples at room temperature. The same batch of graphite constitutes the core of a graphite calorimeter, which is currently being realized to measure the absorbed dose due to ionizing radiation. Two different experimental procedures have been applied. In the first method the specific heat capacity of graphite was measured directly, where its value is corrected for the influence of impurities. The second method, to our knowledge not previously applied to macroscopic samples, is based on a series of differential measurements where no correction for added impurities is needed. By its nature, the second method reduces systematic effects. The specific heat capacity of a particular graphite sample is determined to be 706.9 J K −1 kg −1 with a combined relative standard uncertainty of 9 parts in 10 4 at 295.15 K. The specific heat capacity of cyanoacrylate has also been determined.

“…It is possible to conclude that the temperature presents a significant effect on the static strength of the adhesive joints. In fact the mechanical properties of the cyanoacrylate adhesives depend significantly on the temperature [30,31], as a consequence of the depolymerization that occurs [31], and consequently a cohesive failure is present in terms of typical failure (Figure 6).…”

This article is concerned with the influence of surface treatment on the strength of single lap joints. The tensile tests were carried out in order to find the surface treatments which maximize joint strength using polypropylene reinforced glass fiber as adherents. The maximum shear strength was obtained with the trichlorethylene plus primer treatment when using a cyanoacrylate adhesive. The pretreatment effectiveness was evaluated in terms of environmental durability and an important decrease in static strength of adhesive joints occurred when they were immersed in water.
