1938年,在美国新泽西州杜邦公司一位年轻的科 学家从他研究成功的一种新冷冻剂中发现了一 种稍带脂触感的白色粉末——聚四氟乙烯(TEFLON)。这种物质几乎不与别的任何东西发生反应。当把它作为不粘涂层涂在炊具上时,奇迹发生了,一天无论蒸炸煎炒,炊具的表面都不会粘上任何东西,这较之那些必须用洗碗巾或锅刷使劲清洗,甚至还得先泡上几个小时的铁锅、铝锅之类的烹饪具来说显得
In 1938, a young scientist at DuPont, New Jersey, USA, discovered a slightly fat-spoiling white powder, TEFLON, from a new refrigerant he had successfully developed. This substance hardly reacts with anything else. When it was applied to a cooker as a non-stick coating, a miracle happened. No matter what the day, regardless of steaming and frying, the surface of the cooking utensils would not stick to anything. Compared to those who must use dish towels or pot brushes to clean , it may even be soaked for hours in cooking utensils such as wok and aluminum pan.
