In this paper, different organic-inorganic hybrid materials based in the CaO-SiO(2)-poly(dimethyl siloxane) PDMS system have been characterised by means of nanoindentation and their static mechanical properties (Young's modulus, and hardness) have been investigated. These mechanical properties have been discussed in relation to the chemical composition and structure of the different hybrid materials. Besides, the mechanical behaviour of hybrid materials is visco-elastic and it therefore presents phenomena of creep that will be influenced by the temperature of the mechanical test; undoubtedly, a temperature of 37 degrees C accelerates the processes of creep.
在本文中,基于CaO-SiO₂-聚二甲基硅氧烷(PDMS)体系的不同有机-无机杂化材料通过纳米压痕进行了表征,并研究了它们的静态力学性能(杨氏模量和硬度)。这些力学性能已根据不同杂化材料的化学成分和结构进行了讨论。此外,杂化材料的力学行为是粘弹性的,因此会出现蠕变现象,而蠕变现象会受到力学测试温度的影响;毫无疑问,37℃的温度会加速蠕变过程。
