Carbon Nanotubes Doped with 32 wt% Silicon (Si) and 32 wt% Graphene Nanopowder/Nanoparticles
Carbon Nanotubes doped with 32 wt% Silicon and 32 wt% Graphene nanoparticles combine three powerful functionalities: the high conductivity and mechanical resilience of CNTs, the large surface area and electron mobility of graphene, and the high theoretical capacity and chemical reactivity of silicon. This hybrid structure addresses the limitations of pure silicon (volume expansion) by stabilizing it within CNT networks, while graphene enhances dispersion and conductivity. The result is a multifunctional composite with superior tensile strength, elastic modulus, and electrochemical performance. CNT–Si–Graphene hybrids are positioned as advanced materials for energy storage, electronics, biomedical systems, and composite engineering.

Applications
- Energy Storage: CNT–Si–Graphene hybrids are highly promising for lithium-ion battery anodes, combining silicon’s high capacity with CNT/graphene conductivity to improve cycle life and reduce volume expansion. They also enhance supercapacitors by offering large surface area and fast charge–discharge capability, and support hydrogen storage through hybrid porosity.
- Electronics & Optoelectronics: Applied in transistors, flat panel displays, and solar cells, these hybrids improve charge transport, mechanical stability, and thermal resistance. Graphene’s 2D conductivity and silicon’s semiconducting properties make them suitable for photoluminescence devices and nanofabrication templates.
- Biomedical & Biosensing: CNT–Si–Graphene composites are explored in biosensors for sensitive detection and in drug delivery systems, where silicon’s biocompatibility and CNT/graphene functional surfaces enable controlled release and targeting. They are also studied as nanoprobes for imaging and diagnostics.
- Composites & Structural Materials: In polymer and ceramic composites, CNT–Si–Graphene hybrids improve tensile strength, hardness, and elastic modulus, making them suitable for aerospace, automotive, and construction applications requiring lightweight yet durable materials.
- Catalysis & Environmental: They act as catalyst supports in electrochemical and photocatalytic reactions, leveraging graphene’s conductivity and silicon’s reactivity. CNT–Si–Graphene hybrids are also used in gas-discharge tubes, pollutant remediation, and environmental sensing.
