Abstract: The invention relates to a thoroughly modified, functionalized polymeric hard coating material represented by one of the following formulae for a bendable, transparent and photo/thermal curable coating film:

[R1RaSiO3/2]  Formula (1);

[R1R2RaSiO3/2]  Formula (2).

This invention further relates to the synthetic method and application of the thoroughly modified, functionalized polymeric hard coating material. The thoroughly modified, functionalized polymeric hard coating material-containing composition for a coating exhibits higher surface hardness of at least 6H on flexible substrates, higher surface hardness of at least 9H on rigid substrates, and a certain degree of flexibility, with potential properties such as a light transparency of at least 85% and/or an antimicrobial effectiveness of at least 99%, and/or anti-scratch ability.
