“…Moreover, they do not absorb moisture and are weather resistant. [1][2][3][4] These properties make fluoropolymers the material of choice for products such as heat-resistant cables, chemical-resistant linings, electronic components, cladding materials, and weather-resistant films. [5][6][7] Fluoropolymers include polytetrafluoroethylene, polytrifluoroethylene, polyvinylidene fluoride, polyvinyl fluoride, fluorinated epoxy resin, and so on.…”

Fluoropolymers find applications in heat‐resistant cables, chemical‐resistant linings, electronic components, cladding materials, and weather‐resistant films. Therefore, it is imperative to improve their temperature resistance level and dielectric properties. In this study, a series of new fluorinated epoxy‐phthalonitrile resins with different mass ratios were prepared by adding phthalonitrile to the epoxy resin matrix, followed by a two‐step reaction of the amine with the epoxy resin at low temperature, and then by the reaction of the nitrile with the epoxy resin and the nitrile group at high temperature. The thermal stability and thermal oxidation stability of the cured products were improved; the initial decomposition temperature for 5% weight loss in air was 375.3°C, indicating good heat resistance performance. In addition, the glass transition temperature and storage modulus of the fluorinated epoxy‐phthalonitrile resins cured products increased with an increase in phthalonitrile content. The storage modulus remained above 1500 MPa until 150°C. The glass transition temperature of fluorinated epoxy‐phthalonitrile resins (at a mass ratio of 5:5) was 180°C, much higher than that of the epoxy resin (which was 140°C). Moreover, the dielectric constant of fluorinated phthalonitrile‐epoxy resin (5:5 mass ratio) was 2.01, which was 39.63% lower than that of fluorinated epoxy resin. The thermoset matrix has potential applications in the fabrication of a variety of low dielectric constant composites for electronic device related industries.

“…Although several studies have been carried out in the degradation of some FPs, these studies only examined the thermal stabilities or aging characteristics of the polymers. [7][8][9][10] However, Hori et al recently proposed an interesting technology known as mineralization, which is based on the concept of using FPs to create inorganic compounds that are comparable to minerals. To mineralize the FPs, they applied supercritical water (scH 2 O) and subcritical water (subcH 2 O) in the presence of an oxidant, [11][12][13][14] where the former is defined as water at temperatures and pressures higher than the critical point of 374 °C and 22.1 MPa, and the latter is hot water with a sufficient pressure to maintain the liquid state at temperatures ranging between 100 and 374 °C.…”

“…In PECVD process, thin films can be produced as coatings directly on the desired substrates. [18][19][20][21][22] In this study, because of all these advantages of PECVD method, it was employed to synthesis PI thin films. 2-methyl-1,3-butadiene (isoprene) was chosen as monomer because of its high-vapor pressure (650 hPa at 20 C).…”

Rubber is one of the most commonly used industrial materials worldwide. However, there is a gap in the literature on the production of rubber thin films in nanoscale. When the rubber thin films are produced in nanoscale, they can be used in high-tech applications where bulk rubbers have never been used before. This study is one of the first investigations to focus on the vapor-based production of the polyisoprene (PI), which is an important member of the synthetic rubber class. For this purpose, a single-step, rapid and environmentally friendly method based on plasma enhanced chemical vapor deposition (PECVD) was employed to produce PI thin films using 2-methyl-1,3-butadiene (isoprene). The high-vapor pressure of isoprene makes it a promising monomer for the production of chemical vapor deposition polymers. The effect of plasma processing parameters on the PI deposition rate was investigated. The deposition rate of PI thin film as high as 40 nm/min was achieved and the contact angle of PI coated bamboo surface was found to be 146.8. The mechanical durability and laundering tests of PI thin films were performed. Based on this study results, PI thin films produced by PECVD can be used in a number of potential applications.
