Problems solved by technology

However, these methods are difficult to meet the practical application requirements in terms of the stability of the composite film, the preparation of high-density semiconductor particles, and the control of the aggregation of particles on the film surface; due to the grafted film thickness, narrow molecular weight distribution, uniformity, and high surface The controllability of densification and components, etc., the surface-initiated atom transfer radical polymerization technology (SI-ATRP) with active characteristics has great advantages in this regard

Abstract

The invention relates to a polyester film, which belongs to the technical field of surface modification of organic film materials, and in particular to a preparation method for a surface-grafted polyacrylic acid lead polyester film. The invention provides a preparation method for a surface-grafted polyacrylic acid lead polyester film, which can contribute to realizing uniform surface grafting and has high grafting density. The method is characterized in that: the polyester film material is subjected to a series of surface treatment, a bromo-ester initiator is fixed on the surface of the polyester film material, and polyacrylic acid lead is grafted to the surface of the polyester film with a surface initiated atom transfer free radical polymerization method. The method has a simple process and a good modifying effect. By grafting the polyacrylic acid lead with a cross-linked structure formed by ion bonds on the surface of the polyester film with the method, the surface electrics and surface free energy of the polyester film can be improved effectively, and the surface performance of the modified polyester film can be controlled by changing reacting time.

Description

technical field [0001] The invention relates to a polyester film, which belongs to the field of surface modification of organic film materials, in particular to a method for preparing a surface-grafted lead polyacrylic acid polyester film. Background technique [0002] Polyester film has good mechanical properties, excellent optical properties and electrical insulation properties, excellent mechanical properties in a wide temperature range, good friction resistance and dimensional stability, low wear and high hardness, toughness in thermoplastics It is the best in the film, because the polyester film has so many excellent physical and chemical properties, and the price is relatively low, it is widely used in many fields. [0003] The introduction of functionalized modified polymer films with organic semiconductor metal salts with a cross-linked structure has high application value in the preparation of devices with optical, electrical, and magnetic properties, making its res...
