The organic silicon material has a unique structure:
(1) Sufficient methyl groups on Si atoms shield the high-energy polysiloxane main chain;
(2) C-H has no polarity, which makes the intermolecular interaction force very weak;
(3) The Si-O bond length is longer, and the Si-O-Si bond angle is larger.
(4) Si-O bond is a covalent bond with 50% ionic bond characteristics (covalent bond has directionality, ionic bond has no directionality).
