“…The cyanoacrylate is an effective commercial adhesive for bonding metal and rubber. The cyanoacrylate has the tensile bond strength of 12 to 3 MPa in temperature range of 25°C to 150°C and 13 to 11 MPa in the range of 40% to 100% relative humidity on mild steel substrates . By comparing the stress applied to the contact patch and the bond strength of the cyanoacrylate, it is obvious that cyanoacrylate is a reliable choice for connecting the PEH to the inner surface of the tire for various temperatures and humidities.…”

Summary Basic parameters affecting vehicle safety and performance such as pressure, temperature, friction coefficient, and contact‐patch dimensions are measured in intelligent tires via sensors that require electric power for operation and wireless communication to be synchronized to the vehicle monitoring and control system. Piezoelectric energy harvesters (PEHs) can extract a fraction of energy that is wasted as a result of deflection during rolling of tires, and this extracted energy can be used to power up sensors embedded in intelligent tires. A new design of PEH inspired from Cymbal PEHs is introduced, and its performance is evaluated in this paper. Cymbal PEHs are proven to be useful in vibration energy harvesting, and in this paper, for the first time, the modified shape of Cymbal energy harvester is used as strain‐based energy harvester for the tire application. The shape of the harvester is adjusted in a way that it can be safely embedded on the inner surface of tires. In addition to the high performance, ease of manufacturing is another advantage of this new design. A multiphysics model is developed and validated to determine the output voltage, power, and energy of the designed PEH. The modeling results indicated that the maximum output voltage, the maximum electric power, and the accumulated harvested energy are about 3.5 V, 2.8 mW, and 24 mJ/rev, respectively, which are sufficient to power two sensors. In addition, the possibility is shown to supply power to five sensors by increase in piezoelectric material thickness. The effect of rolling tire temperature on the performance of the proposed PEH is also studied.

“…These adhesives require no heat, pressure, or addition of catalysts to cure. There are some general ways to increase the heat resistance of polymers (5)(6)(7). The cyanoacrylate esters are distinguished from the other olefinic monomers by their ability to undergo rapid anionic polymerization initiated by mild nucleophiles, even in the presence of contaminants like water and oxygen, which efficiently inhibit most other anionic polymerizations (3).…”

Polyalkyl 2-cyanoacrylates begin to retropolymerize and deteriorate dramatically at temperatures above 80°C. They bond rapidly to the metal surfaces and readily lose strength even at ambient temperatures. These two drawbacks of the cyanoacrylates have made this class of adhesives unpopular as structural adhesives. Several attempts have been made to increase the thermal stability and the stability of the bond between the metal surfaces by adding chemicals like cyclopentadienoates and anhydrides to the cyanoacrylates. Cyclopentadienoates are not available commercially, and, therefore, in this study, we have selected various acrylates and methacrylates in the cyanoacrylate formulation and these were tested to various temperatures. Interesting results have been obtained and reported.

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.
