As a new material, nano materials have been paid more and more attention by scientists. After continuous exploration and research, nano materials have been applied to popular industries such as textiles, new energy, medical treatment, electronic information and so on. So, what kind of contribution will nano materials make in the military? "Composite armor": nano ceramics In the future war, armored vehicles and tanks will still be the main force on the land battlefield. But the difference is that the chariot shell is equipped with nano ceramics. Compared with ordinary ceramics, nano ceramics overcome the brittleness of ordinary ceramics and have many advantages that ordinary ceramics do not have. In particular, composite nano ceramic technology mixes ceramic nanoparticles and nanoparticles of other materials for sintering, which can obtain many new ceramic materials with special purposes, with a series of advantages such as high plasticity, high temperature resistance, strong conductivity and so on. Nano ceramic armor used in combat vehicles has higher strength and toughness than ordinary composite armor. It not only further improves its bulletproof performance, but also has lighter mass than the current tank composite armor, which means that this combat vehicle will have higher flexibility. "Invisible coat": nano coating In the future war, combat aircraft will still be the main military force in air combat. In addition to flying higher and faster and causing stronger damage, it will also use microwave absorbing materials to deal with sharp radar detection, so as to achieve "stealth" and surprise the target. These fighters use microwave absorbing materials made of nano materials and sprayed with nano coatings. Nano absorbing materials and nano coatings have the characteristics of internal porosity, which makes it difficult for radar waves to reflect back to the ground. Through the use of these two materials, with the unique smooth and round shape of the aircraft, the radar wave is "gone without return". The blessing of these two materials has greatly increased the threat of "stealth aircraft". At present, the B-2 bomber using the second generation stealth technology adopts these two methods for "stealth". "Space eye": nano satellite In the future space, nanosatellites will become super "observers" in the vast galaxy of stars. Nano satellite is characterized by small size and powerful function of a single satellite. After multiple satellites form a constellation, they can realize and surpass the function of a large satellite. The greater the weight of the satellite, the greater the cost and difficulty of launching, so the satellite is developing in the direction of lightweight. The volume of nano satellite is very small. The weight of a single part is less than 0.1kg, and the overall weight is about 10kg. It can be described as small and exquisite. All components are made of nano materials and integrated with the most advanced MEMS integration technology, which has the advantages of reconfigurability and regeneration, low cost, good quality and stronger reliability. Compared with traditional satellites, nanosatellites have the characteristics of low cost, low energy consumption, more timely information transmission, strong adaptability and wide range. They can play an important role in the military. "Fully armed": future soldiers In the future, a group of soldiers wearing nano combat clothes will appear on the battlefield. Nano materials have higher strength than other materials. Combat clothes made of nano fibers and other nano materials can even easily resist the attack of bullets or some other types of weapons, so that soldiers wearing nano combat clothes can reduce their damage. Nano combat clothing can not only be bulletproof, but also install a microcomputer and ultra-high sensitivity sensors in the combat clothing, which can help soldiers avoid danger more easily. The fibers of nano combat clothing have the special structure of nano materials and have chemical protection characteristics. The fibers treated by nanotechnology can keep the toxins released by biological and chemical weapons out of the body while allowing fresh air to pass through. "Pocket aircraft": nano aircraft In the future battlefield, in addition to these visible enemies, there are "tusks" lurking in the dark and invisible to the naked eye, namely "pocket aircraft" and "ant soldiers". "Pocket aircraft" is a kind of pocket aircraft the size of insects. It can carry various detection equipment and has the ability of information processing, navigation and communication. Its main function is to secretly deploy inside and near the enemy's information system and weapon system to monitor the enemy's situation. Various devices and functions on the "pocket aircraft" are masterpieces of nanotechnology. A "mosquito missile" carried by it is a micro missile shaped like a mosquito manufactured by nanotechnology. It can sneak into the interior of the target unknowingly, and its power is enough to blow up important targets and even strategic targets such as enemy artillery, tanks, aircraft, headquarters and ammunition depots. "Ant soldier": nano robot "Ant soldier" - Nano robot is a terrible existence. It also uses nanotechnology. It is highly permeable and destructive. Its biggest feature is that its energy drive comes from sound energy conversion. It can move with sound. The micro electronic intelligent system enables it to move in various ways. Nano robots can also be equipped with corrosive or conductive liquid to cause great damage or complete failure to enemy weapons. MEMS equipped with micro detector and micro transmitter can be made into insect shape and can fly and crawl. In the future battlefield, these "ant soldiers" can be put in a large number. They can use the tactics of mass attack to cooperate with nano mines and nano bombs to carry out strategic attack, which has great destructive power. "Ant soldier" can carry acoustic sensors, cameras, infrared detectors, high explosives, biological viruses and other weapons. Its power source is the solar cell on its back. At present, weapon experts in some developed countries are making every effort to develop "ant soldiers". "Rescue expert": nano medicine Military strength is not only reflected in the front-line battlefield, but also the medical technology of logistics support forces is very important. Nanotechnology also has a broad world. For example, disinfection drugs containing nano materials can prevent further wound infection; Nano medical robot uses its own characteristics to remove virus cells or cancer cells in human tissues. This nano robot may replace some surgical operations to repair injured organs. In fact, many of the future military technologies mentioned above are not far away from us. Nano materials, a new material supported by nanotechnology, have been widely used in many military weapons, and some research has even reached the testing stage. It is believed that nanomaterials will be sought after by more scientists in the future, and countries will take nanotechnology as the main research direction of military science and technology, making it a force that can not be underestimated to enhance comprehensive national strength.
