Engineering Contradiction Analysis
1Ease of operation
If a fluorine-containing ether compound with a perfluoropolyether chain and hydrolyzable silyl group is used as a surface treating agent, then water/oil repellency and fingerprint removability are improved, but antifriction properties and light resistance are insufficient
Solution Approach 1:
The patent employs a composite molecular structure combining a perfluoropolyether chain (providing low surface energy for fingerprint removability) with a hydrolyzable silyl group (enabling covalent bonding to substrate). This composite structure creates a surface layer that simultaneously achieves both fingerprint removability and enhanced antifriction properties through strong substrate attachment.
Solution Approach 2:
The patent modifies the molecular parameters of the fluorine-containing ether compound by introducing specific structural features (perfluoropolyether chain length, silyl group configuration) that optimize the balance between surface energy characteristics (for fingerprint removability) and mechanical durability (for antifriction properties and light resistance).

3Ease of operation
If a fluorine-containing ether compound is used to form a surface layer, then initial water/oil repellency is achieved, but performance deteriorates under repeated rubbing
Solution Approach 1:
The patent applies preliminary action by using the hydrolyzable silyl group to form strong covalent bonds with the substrate before any rubbing occurs. This preliminary bonding ensures that the fluorine-containing ether compound remains firmly attached to the substrate during subsequent rubbing, preventing premature degradation of water/oil repellency performance.
Solution Approach 2:
The patent employs a composite molecular structure where the hydrolyzable silyl group provides strong substrate attachment (ensuring durability) while the perfluoropolyether chain provides low surface energy (ensuring water/oil repellency). This composite structure maintains performance under repeated rubbing.
