Características da estrutura oca do poliéster conjugado oco

1. Low density: The presence of the hollow structure makes the material contain a large amount of air or cavity, which significantly reduces the overall density of the material. For example, compared with solid polyester materials, the density of hollow conjugated polyester is much smaller, which makes it advantageous in some application scenarios with strict weight requirements, such as in the aerospace field, where it can be used to manufacture lightweight Componentes, o que ajuda a reduzir o peso geral da aeronave e melhorar a eficiência de combustível .
2. High specific surface area: The hollow structure gives the material a large specific surface area. The increase in specific surface area means that the contact area between the material and the external environment increases, which may bring about changes in various properties. On the one hand, in the field of adsorption, the high specific surface area gives it a stronger adsorption capacity, which can be used to adsorb certain substances in gases e líquidos, como adsorvendo substâncias nocivas no tratamento de águas residuais; Por outro lado, em reações catalíticas, sites mais ativos são expostos ao exterior, o que pode melhorar a eficiência catalítica e acelerar a taxa de reações químicas .
3. Good thermal insulation performance: The thermal conductivity of air is relatively low, while the hollow part in the hollow conjugated polyester is filled with air. This is equivalent to forming tiny thermal insulation areas inside the material, which hinders the transfer of heat. Therefore, hollow conjugated polyesters usually have good thermal insulation properties and can be used in building insulation materials, Materiais de embalagem de isolamento térmico e outros campos, o que ajuda a reduzir a perda de calor ou a intrusão e reduzir o consumo de energia .
4. Propriedades ópticas exclusivas: a estrutura oca pode afetar a propagação e a dispersão da luz, de modo que o poliéster conjugado oco exiba propriedades ópticas exclusivas ., por exemplo, alterações nos materiais, e a refração, a reflexão e a dispersão da luz, que possuem um valor possível em), e), que são usados ​​em). Elementos ou produtos com efeitos ópticos .
5. Adjustability: By changing the parameters in the preparation process, such as reaction conditions, template selection and use, etc., the size, shape, wall thickness of the hollow structure, and the size and distribution of the hollow part can be regulated to a certain extent. This adjustability enables hollow conjugated polyester materials with specific structures and properties to be customized according to different needs and Cenários de aplicativos para atender aos diversos requisitos .
