1：Experimental Design and Method Selection:

The study involved synthesizing carbonaceous spheres via hydrothermal carbonization, coating them with mesoporous silica, and preparing hybrid films through sol-gel processes. Techniques like DLS, XRD, SEM, TEM, Raman spectroscopy, and FTIR were used for characterization, and dielectric properties were measured using broadband dielectric spectroscopy.

2：Sample Selection and Data Sources:

Carbonaceous spheres were synthesized from glucose and cyclodextrin mixtures with varying cyclodextrin contents (0%, 10%, 20%). Hybrid films were prepared by blending these with organosilicone.

3：List of Experimental Equipment and Materials:

Equipment includes autoclave, centrifuge, vacuum oven, ultrasonic bath, DLS system, XRD diffractometer, TEM, SEM, Raman spectrometer, FTIR spectrometer, TGA analyzer, BET analyzer, and dielectric spectrometer. Materials include glucose, cyclodextrin, CTAB, TEOS, ammonia, hydrochloric acid, MTMS, PhTMS, hydroxyl silicone, ethyl acetate, ethanol, and deionized water.

4：Experimental Procedures and Operational Workflow:

Hydrothermal synthesis of CSs, silica coating via CTAB-assisted method, calcination, sol-gel preparation of hybrid films, and characterization steps as detailed in sections 2.2 to 2.
