Hydrophilic means "water-loving." Hydrophilic substances have an affinity for water and tend to mix or dissolve in water. This is due to their ability to form hydrogen bonds or other favorable interactions with water molecules. In polymer chemistry, hydrophilic polymers are often used in applications where water solubility or water absorption is desired, such as hydrogels, drug delivery systems, and personal care products.

亲水的意思是“亲水”。亲水性物质对水有亲和力，并且倾向于与水混合或溶解在水中。这是由于它们能够与水分子形成氢键或其他有利的相互作用。在高分子化学中，亲水性聚合物通常用于需要水溶性或吸水性的应用中，例如水凝胶、药物输送系统和个人护理产品。
