Organic Silicone Structure



Silicones are compounds that contain si-c bonds and have at least one organic base that is directly connected to the silicon atom, and are often used as silicones for compounds that connect organic to silicon atoms by oxygen, sulfur, and nitrogen. Among them, polysiloxane with silicon oxygen bond (-si-o-si-) as the skeleton, is the most of silicone compounds, the most research, the most widely used category, about 90% of the total dosage.

Silicone materials have a unique structure:

(1) sufficient methyl atoms on the SI atom will shield the high energy polysiloxane main chain;

(2) H of the polarity, so that the interaction between molecules is very weak;

(3) The SI key length is longer, the SI key angle is big;

(4) The SI bond is a covalent bond with a characteristic of 50% ionic bonds (the covalent bond has directionality and the ionic bonds have no directionality).
