The researchers studied the webs under both electron and light microscopes. They noticed that as water condenses on the web, droplets move towards the nearest spindle-knot, where they coalesce to form larger drops.
WebThe height and width of the knot increase and the interval decreases with increasing the flow rate ratio and the microdroplet diameter. The viscosity of the oil phase plays an important role in the successful formation of the knots. The alginate fibers with spindle-knots exhibit water collection capability. WebAug 12, 2015 · Moreover, the dehydrated spider-silk-like microfibers, with magnetic spindle-knots for collecting water drops, can be controllably assembled into spider-web-like structures for excellent water collection. These spider-silk-like microfibers are promising as functional building blocks for engineering complex 3D scaffolds for water collection ...
