Dear Ivo MING LING Ting

May I contribute by adding a fully adopted paragraph from the Occupational Health & Safety site on Google link:

https://ohsonline.com/Articles/2006/04/More-Grip-Less-Force.aspx?Page=3

"A new glove technology allows workers to apply significantly less force and still effectively grip wet or oily objects. The technology involves adding a roughened surface comprised of microscopic channels in a patented ultra-thin nitrile coating to gloves to direct fluids away from the grip surface.

The technology works in a manner similar to tire treads cutting through water on a roadway, with the channels propelling oils and other lubricants away from the pressure surface. This provides a relatively dry contact area that allows workers to maintain almost the same grip in oily applications they would have in dry conditions."

Best regards

You have to provide some kind of surface modification to remove liquids from contacts like in tyre-road interface.

As other researchers suggest surface modification is the technique for your problem. Now there are different ways of modifying a surface. If you can come up with some novel method to provide a path for water to slip away from the hand gloves then friction increases. You can certainly refer to the patterns on tyre and footwear to get an idea about how those functions. Then depending upon your use case you can invent a new pattern.

All the best.

Just little heat the tips of finger and press on a meshy grid metal. It can gives little chance to increase friction.
