Abstract

Competitive sports has always been the front line of high-tech applications, from electronic timers to "shark skin" swimsuits, from "bird's nest" and "water cube" to blood lactic acid detectors; from electronic science to material science, from architecture to biology chemistry. To find more suitable sports equipment materials, we prepared the composite multiferroic material 0.2NiFe₂O₄/0.8BaTiO₃ by solution casting, spin coating, and hot pressing, and used various instruments to understand its various properties. The study found that the two exothermic peaks of the material in the range of 110–220 °C are attributed to the large amount of adsorbed water and the degradation of hydroxyl compounds. The 20% weight loss associated with the strong exothermic peak at 300 °C is due to the degradation of inorganic salts and citric acid. What is more worth mentioning is that there is almost no weight loss when the temperature exceeds 340 °C, which proves that 80% of the total mass of organic species (such as: citric acid), inorganic nitrates, and other adsorbents (such as: water, ethanol, etc.) have been completely removed. In addition, the heat treatment process can change the crystallinity and physical and chemical properties of the material. In competition sports, 0.2NiFe₂O₄/0.8BaTiO₃ material has the characteristics of good bounce and excellent balance. It can be applied to ski poles. Its good ductility and light weight make it very useful in bow, arrow and hull design space. In folk sports, 0.2NiFe₂O₄/0.8BaTiO₃ composite sports equipment can be widely used in various sports and various types of sports equipment.

摘要

竞技体育一直是高科技应用的前沿，从电子计时器到“鲨鱼皮”泳衣，从“燕窝”和“水立方”到血乳酸检测仪；从电子科学到材料科学，从建筑学到生物化学。为了寻找更合适的运动器材材料，我们制备了复合多铁材料0.2NiFe ₂ O ₄ /0.8BaTiO ₃通过溶液浇铸、旋涂和热压，并使用各种仪器了解其各种性能。研究发现，材料在110~220℃范围内的两个放热峰归因于大量吸附水和羟基化合物的降解。与 300 °C 的强放热峰相关的 20% 重量损失是由于无机盐和柠檬酸的降解。更值得一提的是，当温度超过 340 ℃时几乎没有重量损失，这证明有机物（如：柠檬酸）、无机硝酸盐和其他吸附剂（如：水、乙醇等）已被完全去除。此外，热处理工艺可以改变材料的结晶度和物理化学性能。₂ O ₄ /0.8BaTiO ₃材料具有弹跳性好、平衡性好等特点。它可以应用于滑雪杖。其良好的延展性和重量轻，使其在弓箭和船体设计空间中非常有用。在民间体育运动中，0.2NiFe ₂ O ₄ /0.8BaTiO ₃复合运动器材可广泛应用于各种体育运动和各类运动器材。
