Functional materials<\/a><\/strong> represent one of the most dynamic sectors in polymer research, development, and production. Ultrafine powder<\/strong> is not only a functional material in its own right but also a critical component in advanced composite materials. Its unique properties allow it to play a vital role across various sectors of the global economy.<\/p>\n\n\n\n

I. Properties and Applications of Ultrafine Powders<\/h2>\n\n\n\n

1. Surface Characteristics<\/h3>\n\n\n\n

Ultrafine powder science and technology have emerged as a new discipline in recent years and form an essential part of materials science. Although definitions vary, powders with particle sizes >1\u202f\u03bcm are generally called micron powders; those between 0.1\u202f\u03bcm and 1\u202f\u03bcm are submicron powders; and those <100\u202fnm are nanopowders. Some also classify powders <3\u202f\u03bcm as ultrafine powders. There are three types of ultrafine powders: micron, submicron, and nano powders. The relationship between particle size and properties is as follows.<\/p>\n\n\n\n

2. Surface Structure and Chemical Activity<\/h3>\n\n\n\n

Crystalline structures\u2014categorized as close-packed, skeletal, layered, or chain structures\u2014break along their weakest bonding points when subjected to external force. This cleavage creates unsaturated bonds<\/strong> (uncompensated broken bonds) on the fresh surface.<\/p>\n\n\n\n
