This invention disclosed medical catheters with surface hydrophilic coatings. Said catheters were grafted with a thin layer of zwitterions, which forms lubricious water layer when contacted with human body liquids or other water solutions, to lower the surface friction and mechanical damage to human body. One benefit of the present invention is due to the excellent biocompatibility and tight bonding between modification material and catheter substrate, the modification will stably stay on the substrate during usage, to avoid the potential side effects caused by lubricants. This modification can be applied to multiple material surfaces, including but not limited to silicone rubber, polyurethane, rubber, polyetheretherketone, polyethylene, polypropylene, polyvinyl chloride, nylon, ABS (Acylonitrile Butadiene Styrene), and polycarbonate.

Provided is a method for mitigating a lost circulation zone. The method may include providing a lost circulation treatment composition that may include an acid responsive polymer that may include at least one monomer, at least one comonomer, and at least one crosslinker; a carbonate-based solvent; and a carrier fluid that may include water. The method may also include introducing the lost circulation treatment composition into a wellbore within a subterranean formation, wherein the subterranean formation may include the lost circulation zone; placing the lost circulation treatment composition into the lost circulation zone, hydrolyzing the carbonate-based solvent to generate carbon dioxide, and causing the swelling (change of shape) of acid responsive polymer to mitigate the losses.
