UV-curable coatings (UV coating ) due to high efficiency , energy saving, environmental protection , economic and other advantages, as well as film excellent scratch resistance , chemical resistance , light , etc., have been widely used in mobile phones , tablet computers and other consumer electronic products surface of the varnish . However, in the course of these products easy to leave fingerprints , skin oils , ink and other stains . Therefore, people are stain resistant UV coatings keen interest . Anti-stain coatings research focuses on silicone and organic fluorine coating . Fluorocarbon acrylate polymer based low surface energy , super hydrophobic oleophobic , has received attention. In this paper, reversible addition fragmentation chain transfer (RAFT) controlled polymerization to prepare a series of controlled structure acrylate - Fluorocarbon acrylate block copolymer ; using the \dobby star - block copolymer. Nuclear magnetic resonance , gel permeation chromatography were used to characterize them . With differential scanning calorimetry (DSC), atomic force microscopy (AFM), the contact angle test , the system of the polymer chain structure of micro phase separation , the surface morphology of the coating surface morphology and anti- staining properties of the corresponding relationship , the results showed that: ( 1) Since P (MA-ran-nBA) and PFAEA incompatibility , so that the synthetic fluorocarbon acrylate block copolymers have relatively distinct microphase separation structure, and to have a specific the molecular chain structure with only a few FAEA unit fluorocarbon acrylate block copolymer having a specific structure can be constructed on the surface , to be added to the formulation cured film , the coating and the water contact angle of maximum energy of 110 °. ( 2 ) from the natural surface hydrophobicity biomimetic leaves the phenomena , the synthesized acrylic fluorocarbon dobby star - block copolymer coating having a diameter of 40 ~ 70nm projection granular structure, morphology relative to the fluorocarbon neat and orderly acrylate block copolymer , added to the formulation to be cured film , the film contact angle with water can reach 116 °. Dobby fluorocarbon acrylate block and star - fluorinated block copolymer components in the migration to the surface during the curing process , forming a micro - nano structure stain resistant hydrophobic and oleophobic coatings, anti-fingerprint coating , good anti- stain skin oils .
