BEIJING-Chinese scientists have developed new biomimetic polypropylene foams for oil-water separation, which can be used to prevent and control oil pollution. Oil-water separation is a global challenge due to increasing industrial oil-containing waste water and frequent oil spills. Consequently, research on high-efficiency oil-water separation materials and technologies has scientific significance and application value.

Some conventional methods for tackling oil pollution such as combustion and filtration have shortcomings including high energy consumption, long duration and possible secondary pollution. Scientists from the Ningbo Institute of Materials Technology and Engineering under the Chinese Academy of Sciences have designed new biomimetic polypropylene.
