Polyimides (PIs) are high-temperature engineering polymers originally developed by the DuPont™ Company. PIs exhibit an exceptional combination of thermal stability (>500°C), mechanical toughness, and chemical resistance. They have excellent dielectric properties and inherently low coefficient of thermal expansion. They are formed from diamines or diisocyanates and dianhydrides such as those shown in the picture.
There is more than one type of polyimide. Today we are going to talk about the polyimide resin and polyimide film. The chart below just shows the comparisons.
Polyimide film could be made from polyimide resin. The resin is first dissolved in a solvent and then cast onto a substrate. The solvent is then evaporated, leaving behind a thin film of polyimide. The film is then annealed, which helps to improve its properties.
The connection between polyimide film and polyimide resin is that they are both made from the same basic materials. The difference is that the film is a thin, flexible sheet, while the resin is a more viscous liquid.
Polyimide film and polyimide resin have many of the same properties. They are both heat-resistant, strong, and chemically resistant. They are also both transparent to a wide range of wavelengths.
However, there are some differences between the two materials. Polyimide film is more flexible than polyimide resin. This is because the film is made from a thinner layer of material. Polyimide resin is also more viscous than polyimide film. This means that it is more difficult to work with.
Polyimide film and polyimide resin are both valuable materials with a wide range of applications. They are used in a variety of industries, including electronics, aerospace, and medical devices.

N-phenylmaleimide produced by Yangchen Technology can be used in antifouling of marine warships.The specification is greater than 98%.
Initially, modified acrylic resin (PAZ/ N-PMI). Composite coating samples were prepared by dispersing fluorinated silica-coated hydroxylated multi-walled carbon nanotube nanocomposites (F-MWCNTs-OH@SiO2) in PAZ/N-PMI resin. The composite coating showed good performance, and the antibacterial rate of the composite coating against Staphylococcus aureus and Escherichia coli was >99.98%. When the F-MWCNTs-OH@SiO2 content is 3 wt%, the Zf=0.01Hz of the composite coating reaches the highest value, which is 3 orders of magnitude higher than that of the PAZ/N-PMI coating. At the same time, the prepared composite coating also showed good self-healing properties. This research provides broad application prospects for the development of high-quality marine anti-corrosion and anti-fouling organic coatings.
Acrylic resin coatings play an important role in metal protection due to their low cost, safety, environmental protection, and good weather resistance. However, its poor thermal stability and weak antifouling performance greatly limit its practical application in engineering. However, the metal structures of marine ships and various coastal steel structure engineering equipment have been exposed to complex and harsh marine environments (high salt spray, humidity, strong winds) for a long time. Therefore, corrosive media and external stress will damage the coating surface, causing the coating to crack and fall off. Therefore, the corrosive medium is more likely to penetrate into the coating and reach the metal matrix, causing the protective function of the coating to fail. Therefore, the self-healing function is very important for protective coatings because it can repair damaged parts, extend the protective life, and reduce the maintenance cost of the coating. However, there are few reports on the use of self-healing coatings for marine anticorrosion and antifouling.
Research has demonstrated that embedding bactericidal functional groups into polymers can effectively inhibit microbial adhesion, making it a significant development for antifouling applications. N-phenylmaleimide (N-PMI) has become a hot topic in polymer material modification research due to its good thermal stability, good antibacterial properties, and no environmental pollution. From a structural point of view, N-phenylmaleimide (N-PMI) is a five-membered ring monomer with a 1,2-disublimate vinyl structure. N-PMI can react with acrylic monomers to form polymers. N-PMI is also a heat-resistant polymerizing monomer. Embedding it into the polymer chain can increase the internal ring resistance of the polymer chain, limit the movement of the polymer molecular chain, and improve the thermal stability of acrylic resin. N-PMI has extensive antibacterial activity against microorganisms such as Escherichia coli and Staphylococcus aureus, and can effectively inhibit the reproduction and growth of microorganisms for a long time.
This new acrylic composite coating will effectively reduce marine corrosive media and marine fouling biomass on marine ships and engineering equipment, and increase their service life.
