Design of a Practical Superhydrophobic Coating of Inorganic-Oxide Nanoparticles in a Polymer Matrix with Chain-Reinforcing Adaptability
摘要
The design of a superhydrophobic coating of inorganic-oxide nanoparticles in a polymer matrix with practical usability, including robust superhydrophobic properties, abrasion resistance, ultraviolet resistance, durability and stability has been achieved. This was inspired by the broad spectrum of interactions found in biopolymers especially the interactions of polymeric chains which result in biopolymers adaptable to the change in environments. This goal was realized by creating polymeric methacrylate chains in a traditional superhydrophobic coating which reinforced the flexibility and adaptability. The results showed that the proposed coating provided enhanced physicochemical properties in contrast to the traditional superhydrophobic coating, allowing for stronger superhydrophobic properties (nearly comparable to lotus leaves, with a contact angle of 159.2°), better abrasion resistance (increased by up to 4.4 times) and ultraviolet resistance (increased by up to 3.5 times). The proposed coating also exhibited excellent durability and stability when exposed to a strong acid and a strong base. The improved superhydrophobic properties, abrasion resistance and ultraviolet resistance, in combination with the excellent durability and stability, suggest a promising route to developing sophisticated superhydrophobic coatings for applications, particularly involving abrasion, erosion, ultraviolet exposure and environmental conditions.
