Product details

1. Structural properties:

Polydimethylsilane is a kind of organic silicon polymer whose main chain consists of si-si bonds and all side chains are methyl groups, presenting white powder and insoluble at room temperature. It has high crystallite and non-melting characteristics. Because of the lower electronegativity of Si and 3D unoccupied orbital, a special structure containing conjugated system inσelectron delocalization of Si-Si bond in the main chain, making the poly dimethyl silane have photoconductive, third-order nonlinear optics, photoluminescence, electroluminescence and some other features.

2. Product performance:

1 used as photoelectric materials (such as light conductor, electric conductor, led, optical memory material, etc.);

2 production of high temperature resistant ceramic materials;

3 used for fine processing (submicron lithography);

4 used in the field of photochemistry (photoinitiator);

4. Application of polydimethylsilane:

1) SiC ceramics-making;

2) as the initiator of olefin polymerization;

3) as photoconductive and charge transfer composite materials;

4) as a high resolution photoresist;

5) as a non-linear optical material;

6) manufacture of light-emitting diodes;

7) development of new optical memory materials;

8) Polydimethylsilane has also been widely used in other photoelectric materials. In recent years, poly dimethyl silane film is used in contacted scanning probe microscope (SPM) nano-imprint lithography, with advantage of higher solubility and less radiation loss when molding.

Since Poly dimethyl silane is a new functional polymer material, the study whether in theory or in practice has significant meaning. Poly dimethyl silane chemical has become a hot spot in the field of organic silicon, the research on it is very active. With the deepening of research, polydimethylsilane is expected to be widely used in many fields.
