3、 Innovation direction of modified technology
Multi functional group synergistic modification
By introducing various functional groups such as amino groups, epoxy groups, and polyether groups, a "one dose multi effect" modified silicone oil is developed. For example, the "amino epoxy polyether three modified silicone oil" developed by a certain brand has flexibility, cross-linking, and water solubility, making it suitable for complex textile processes.

For example, fabrics containing silicone oil microcapsules can sense temperature changes and automatically adjust breathability; Cosmetics containing silicone oil nanoparticles can achieve "light controlled release".
Biobased and Renewable Modification
Preparation of modified silicone oil using biomass as raw material to reduce carbon footprint. For example, a company has launched a "bio based amino silicone oil" made from corn starch, which has performance comparable to traditional silicone oil but reduces carbon emissions by 50%.
3D printing and customized production
By regulating the rheological properties of modified silicone oil, precise molding of 3D printing materials can be achieved. For example, adding modified silicone oil to a certain photopolymerization resin can improve printing accuracy to 0.1mm and increase surface smoothness by 2 levels.
