PTW is small in size, easy to agglomerate and bridge, and has very poor fluidity. The best mechanical properties of PTW filled PTFE appear when the mass fraction of PTW is between 5% and 10%. In recent years, whiskers have developed rapidly, and many new varieties have appeared, such as potassium titanate PTFE fiberglass adhesive tape (K2O. The addition of PTW improves the hardness of the material to a certain extent, but the difference is not significant. After modification, the surface energy of PTW is significantly reduced, and the dispersibility is greatly improved. 6TiO2), calcium sulfate (CaSO4), calcium carbonate (CaCO3), aluminum borate (9AI2O3 ., and they are a new type of material with great development prospects. Therefore, the surface modification of PTW is indispensable.Whiskers, also known as crystalline fibers, are very thin single crystals, usually only a few microns in diameter. Feng Xin et al. Diao Xiaosong investigated the influence of PTW content on the friction and wear properties, mechanical properties and hardness of PTW/PTFE composites. PTW is a kind of reinforced fiber with excellent performance. Compared with the original SiC, A12O3, and silicon nitride (Si3N4) whiskers, these new types of whiskers have a very good cost performance. studied the performance of potassium titanate whiskers (PTW) reinforced PTFE composites. Between PTW and PTFE The coupling effect of sulphate is worthy of further study.Whiskers are single crystal fibers with few defects, so their mechanical strength is high, and their tensile strength can be close to the theoretical strength of pure crystals. The hardness is the largest when the mass fraction of PTW is 15%, which is about 69 Shore hardness, which is nearly 10% higher than pure PTFE. The thick whiskers are needle-shaped, and the thin whiskers are soft hair-like.2B2O3), magnesium sulfate (MgSO4), TiO2, white gemstones and other products. After being filled with PTFE, the comprehensive performance of the composite material is obviously better than that of pure PTFE and GF/PTFE composite materials. The impact strength and tensile strength of the material are significantly improved with the addition of PTW. Whiskers can be widely used for the reinforcement of plastics, rubber, metal alloys, glass, ceramics and composite materials, etc. For PTW/PTFE with a 5% filling mass fraction, its tensile strength, elongation at break, impact strength, and heat distortion temperature are respectively increased by 19%, 34%, 3% and 9% compared with pure PTFE; while the amount of wear decreases Nearly 10 times. The impact strength is improved more obviously, which is about 50% higher than that of pure PTFE, and the tensile strength is increased by about 30%. When the PTW filling mass fraction is 15%, the impact strength and tensile strength of the composite material are the highest
