Based on general polymers and engineering plastics the strength, flame resistance of the material, its impact resistance, hardness, antibacterial resistance, and aging resistance properties of plastics are enhanced through filling, mixing strengthening, filling and other techniques.
What Nanomaterials can do to modify plastics?
1. Resilience to ageing of reinforced plastics
The process of aging polymer materials especially photooxidation-related aging begins on the outside of products or materials, such as discoloration, cracking, pulverization diminution and so on before gradually advancing into the core. The properties of polymers that prevent aging directly affect their service life and the environment in particular agricultural plastics and plastic construction materials. It’s not only an indicator that deserves the most attention, but a crucial aspect in polymer Chemistry. The wavelength of ultraviolet in sunlight is 200-400nm. The ultraviolet spectrum of 280400nm can cut the polymer molecular chains that causes the material to undergo aged. Nano-oxides, like nano-alumina and nano-titanium oxide and so on, possess excellent absorption capabilities for microwave and infrared. Nano-oxides that are properly mixed with SiO2 and TiO2 can absorb a huge quantity of ultraviolet rays. This helps prevent plastics from being damaged by sunlight. They also assist to protect plastic from cracking, discoloration , and lighting-related damage, making these materials anti-aging.
2. Enhance the characteristics of the antibacterial, anti-mildew, and anti-milde plastics
The preparation of antibacterial plastics is usually by adding antimicrobial agents or masterbatch. This is then added into the resin. Because plastic molding requires to go through high temperature and pressure, there are organic antimicrobial agents that can be adjusted to the extreme temperature. Metal powders that are traditionally used to combat bacteria such as copper sulfate , zinc nutrients are not easy to combine into thermoplastics directly. Inorganic nanoantibacterial powder is treated to make antibacterial plastic masterbatch, which is easy to incorporate into plastic products and has good integration with plastic. It helps in the dispersal of antimicrobial substances. Inorganic silver ions may be transformed into nano titanium dioxide nano-silicon aluminum dioxide and other inorganic nanomaterials. the resultant powder has antibacterial properties. It can be combined with plastics, extruded in the form of ultraviolet radiation creating antibacterial plastics. The antibacterial effects are produced through the gradual release of antimicrobial agents to provide the antibacterial effects.
3. Enhance the strength and toughness of plastics
After the second substance has been added in the polymeric matrix, a composite is formed, and a stronger material can be obtained through compounding which is used to improve the mechanical and impact resistance of the substance. Nanomaterials’ emergence provides the possibility of a novel method for the reinforcement and toughening improvement of plastics. The defects on the surface of the small particle size dispersed phase are comparatively small and there are numerous unpaired electrons. The ratio of surface atomic number to the total number of nanoparticles rises dramatically as particles decrease in size. There is a crystal field-like environment, and the binding energy of surface atoms differ from the ones of internal atoms. This means they have great chemical activity. Thanks to the micronization effect of the field and the increase of active surface atomsand atoms in the crystal, the surface energies increases dramatically, so it can be a close match with the polymer substrate. It also has good compatibility. If exposed to external force, the ion is not likely to be removed from the substrate . It is also able to better absorb the external stress. While at the same time due to the interaction with the stress field the material will develop more microcracks and deformations in the substrate that can cause the substrate’s surface to yield and consume more force, in order to accomplish the goal of toughening and strengthening in the same way. The most popular nano-materials used are nano Alumina, nano silica, nano-calcium carbonate, etc.
4. Enhance the thermal conductivity of plastics
Plastics that are thermally conductive are a type of plastic product with great thermal conductivity. They tend to be higher than 1w/ (m. km.). Thermal conductive plastics are more and more widely utilized because of their lightweight and high thermal conductivity. They also have simple injection moldingand low processing costs and so on. Because of its superior electrical insulation as well as thermal conductivity, nano-alumina has been extensively utilized in thermally conductive plastics, thermal conductive rubber, construction age, thermal conductor coatings and various other areas. Comparatively to metal filler the nano-alumina / nanomagnesia blend can not only increase the thermal conductivity but also enhance the effect of insulation, and the mechanical properties of plastics may also be improved.
5. Improve Plastics’ processability
Certain polymers, such as ultra high molecular weight polyethylene (UHMWPE) having a typical viscosity molecular weights that exceed 150 minutes, possess exceptional comprehensive properties, but they are difficult to be constructed and processed due their highly viscosity. This limit their use and popularity. In order to take advantage of the lower interlaminar friction coefficient of layering silicate sheets, the nano-rare earth/ultra-high molecular weight polyethylene blend was developed by fully mixing UHMWPE with layers of silicate, to reduce the binding of UHMWPE molecular chain , and also reduce the viscosity. It plays a significant role in lubricationand greatly improve the efficiency of its processing.
6. Nanomaterials make plastics functional.
Metal nanoparticles are heterogeneous in their nucleation that can trigger the formation in some crystal forms that impart toughness of the components. When polypropylene is coated with nanoparticles of metal with a low melting point they are discovered to it may play the role of conductive channel. This can help in strengthening and toughening polypropylene and its low melting point improves the processability of the composites.
