Bionic surfaces of PDMS and their application in the field of protection
The design and fabrication of bio-inspired bionic functional surfaces has become an important and fascinating research topic with a wide range of applications in daily life,industry and agriculture in recent years.Polydimethylsiloxane(PDMS)has been widely used for bionic surface modification due to its high flexibility,low surface energy and chemical stability.Herein,the preparation and performance control methods of PDMS with micro-nano rough and smooth biomimetic surfaces were reviewed,followed by introduction on their application fields and the application progress in the fields of anti-corrosion,anti-icing,anti-biofouling and optical protection.The advantages and disadvantages of preparation methods for different PDMS bionic surfaces were compared,and the control strategy of surface properties was described.Finally,the existing problems and future development directions were summarized and discussed.
