Third, the main characteristics Polymer-silicate nanocomposites have excellent strong waste, stiffness, and barrier properties, in addition, compared with the commonly used filler-type reinforced polymer, the former contains a much smaller amount of filler. In reinforced conventional polymers, the required inorganic filler accounts for approximately 20-30% (by weight), and for clay fillers in nanocomposites, at most only one-tenth of the total weight is sufficient to improve the material properties. This is mainly due to the large contact area between the clay and the polymer structure.
According to foreign studies, the 4.7% (weight component) of Jiaoling clay composites were compounded into Nylon-6 polymers. The tensile strength of nanocomposites increased from 68.6 Mpa to 97.2 Mpa, and the flexural strength increased from 89.4. At 143.0 MPa, the thermal transition temperature increased from 65 to 152, and the increase in the heat distortion temperature means that the range of applications for this material is greatly expanded. Some scholars' research results show that the increase in deformation resistance of nanocomposites is due to the existence of a strong interaction between the polymer matrix and the clay filler, and the large surface area of ​​the silicic acid particles forms the physics. status.
Due to the long molecular chain size of the polymer matrix in the polymer matrix, the nanocomposite material is usually also transparent. Some scholars have demonstrated through experiments that the polyimide with 2% (weight component) of colloidal clay has the same transparency as the original polyimide. In addition, the results of further studies show that if the above-mentioned amount is further increased, the transparency will decrease and gradually turn yellow.
The permeability of the nanocomposites is significantly lower than that of the native polymers. The reason is that the sheet-like silicic acid layer interspersed in the polymer lattice structure blocks the flow ability of the diffused molecules, and the presence of the silicic acid layer in the polymer structure greatly increases the diffusion path of the diffusion molecules, and in the silicon The network around the acid fat also reduces people's permeability. Some researchers have described that polyamide-gelatin nanocomposites have high barrier to moisture. According to the results of some studies, polyimide-gelatin nanocomposites formed using 2% (by weight) colloidal clay have less than half of the permeability of pure imide for oxygen, helium, and water vapor. However, the function of nanoparticles is obvious.
Fourth, the application prospects Because nanomaterials have better performance than other similar materials, it broadens the scope of application of the material. According to information, a variety of nano-polymer composite materials have been successfully developed and have been used in automotive, marine and electromechanical components. Undoubtedly, the high barrier properties of the nano-packaging composite materials introduced in this article will be favored and valued in the packaging industry because such materials are firstly suitable for so-called barrier packaging. This type of barrier packaging has a wide range of applications and will be used in the packaging of foods and pharmaceuticals, precision mechanical parts, electronic and electrical components, etc., as well as sealing cap liners and the like. Other potential applications for polymer nanocomposites have been reported, and researchers are developing nanocomposites for aircraft cabins and fuel tanks to improve flight safety and reliability.
The annual consumption of metal beverage cans in the world uses a lot of mineral resources. While improving the performance of metal packaging, efforts to reduce the consumption of materials and reduce processing costs have always been the goals pursued by the packaging manufacturing industry. The plates required for beverage cans have now been developed into so-called third-generation nanoscale plates. Tin-coated particles are only about 100 nanometers in diameter. The volume and amount of tin plating are greatly reduced, and the new plate is easy to process and shape, and the operating parameters range is relaxed. In particular, the improved welding sealability makes it a high-grade metal can plate.
According to another report, the Swedish National Packaging Research Institute is studying polyamide-gelolin nanocomposite films and is intended for food packaging that requires long shelf life. The polymer substrate they use is a biodegradable semi-crystalline thermoplastic polymer. Biodegradable polymer materials have always attracted people's attention and believe that this material is an effective method to solve environmental protection problems. In order to make such materials available for sale in the market, the polymer must also have improved barrier properties. Thus, researchers have come up with the idea of ​​applying nanotechnology, which can be achieved by fusing nanoparticles (choose metal, inorganic or organic) into the polymer lattice structure. In this way, the application of biodegradable packaging materials can be expanded and a good market competitiveness can be achieved.
