Low surface energy materials, such as Teflon (polytetrafluoroethylene) coating, resist the adhesion of oil with its excellent chemical inertness and anti-wetting properties
.
These significant advantages also make it difficult for traditional adhesives to establish ideal bonding strength with them
In view of this Hong Gang Chinese University (Shenzhen) Zhu Shiping and Zhang Qi team put forward by the "ion - introducing adhesive design dipole" role, given its high strength and adhesion to low surface energy materials, can solve the above-mentioned Difficult
.
The research results were recently published in ACS Applied Material & Interfaces (doi: 10.
1021/acsami.
The design research group synthesized adhesive is one kind of fluorine-containing copolymer ( PHFBA- CO.
'S -MMA ) and a hydrophobic ionic liquid ( of EMImTFSI ) group into ion gel
FIG.
1.
( A ) adhesive adhesive bonding principle; ( B ) adhesive is used on the chemical structure of formula; ( C ) of EMImTFSI and HFBA the PTFE surface binding energy
FIG.
2.
By optimizing EMImTFSI and MMA weight fraction, optimum toughness and bonding strength of the strongest adhesive
Figure 3.
( a ) Adhesive performance is closely related to the wettability of ionic liquids; ( b ) and ( c ) are performance comparisons between ionic gel adhesives and commercial adhesives ; ( d ) on different substrates The macro bonding performance on the display
