摘要:
Compositions useful for improving the adhesion of coating compositions, such as dielectric film-forming compositions, include a hydrolyzed amino-alkoxysilane having a protected amino moiety. These compositions are useful in methods of improving the adhesion of coating compositions to a substrate, such as an electronic device substrate.

摘要:
Described are a carbon-iodine conjugated polymer and preparation thereof, an imaging marker thereof, and uses thereof for preparing a localization marker, and belongs to the technical field of imaging markers. The conjugated structure enables the polymer to have strong absorption in a visible light region, and high iodine content of up to 84.1% corresponds to the strong imaging ability thereof. During surgery, on the basis of the dual guidance of a polymer-based image marker and naked eye observation, the marker can better facilitate determination of tumor resection margins, achieving precise resection of tumors and minimizing damage to surrounding normal tissues. During cyberknife-based treatment, the polymer can replace clinical gold markers to provide ray marker guidance. Absence of metal artifacts improves ray imaging quality and the accuracy of radiation dose distribution, good biocompatibility enhances the stability of the relative position of the marker, and radiotherapy side effects can be further reduced.
