Tapes, adhesives, and 2D materials are critical components in modern manufacturing and advanced technologies. Tapes are flexible materials coated with adhesives for bonding, sealing, or insulation. Adhesives are substances used to join materials by surface attachment. 2D materials are atomically thin materials (e.g., graphene, transition metal dichalcogenides) with exceptional electrical, mechanical, and thermal properties. These materials enable innovations in electronics, energy storage, automotive, and biomedical industries.
| Type | Functional Features | Application Examples |
|---|---|---|
| Pressure-Sensitive Tapes | Adhere with light pressure, removable/permament options | Electronic component fixation, packaging |
| Structural Adhesives | High load-bearing capacity, chemical resistance | Aerospace composite bonding |
| Graphene | High conductivity, strength (130GPa tensile strength) | Flex circuits, sensors |
| Molybdenum Disulfide (MoS ) | Excellent lubrication, semiconducting properties | Transistors, catalysis |
Tapes typically consist of a substrate (polyester, foam) with adhesive layers (acrylic, rubber). Adhesives may use epoxy, polyurethane, or silicone chemistries. 2D materials possess layered structures with weak interlayer bonds (van der Waals forces), enabling exfoliation into monolayers. Graphene's sp -carbon lattice provides superior mechanical (Young's modulus: 1TPa) and thermal conductivity (5000 W/m K).
| Parameter | Significance | Typical Values |
|---|---|---|
| Peel Strength (N/mm) | Bond durability assessment | 0.5-10 (tapes) |
| Shear Strength (MPa) | Load-bearing capacity | 5-50 (adhesives) |
| Layer Thickness (nm) | Performance determinant for 2D materials | 0.3-10 (graphene) |
| Electrical Conductivity (S/m) | Electronic application suitability | 10 (graphene) |
Key industries include:

| Henkel | Loctite EA 9466 (aerospace adhesive), Bonderite coatings |
| Graphenea | CVD graphene sheets (95% monolayer purity) |
| 2D Tech | MoS nanosheets for lubrication |
Key considerations: - Environmental resistance (temperature, UV exposure) - Mechanical requirements (flexibility vs. rigidity) - Electrical/thermal conductivity needs - Application-specific certifications (e.g., ISO 10993 for medical adhesives) - Cost-performance balance (e.g., graphene price vs. performance gains)
Emerging developments include: - Bio-based adhesives for sustainability (e.g., soy-based epoxy) - Smart materials with stimuli-responsive properties (pH/temperature-sensitive tapes) - 2D heterostructures for advanced electronics (graphene-hBN vertical stacks) - Miniaturization demands driving nanoscale adhesive solutions - Increasing adoption in flexible electronics (wearables, foldable displays)
