Improved chemical resistance of ink‐jet printed micropatterns on glass by using dual‐functional compositions

Abstract

UV curable and UV/moisture dual‐functional oligomers were synthesized by grafting trimethoxysilane and methacrylate segments on the polyimide oligomer chains. These oligomers and a dual‐functional monomer were used as ink compositions to enhance the chemical resistance of ink‐jet printed LCD color filter micropatterns, without sacrificing jetting performance. The molecular structure and molecular weight of the oligomers were altered to adjust the solubility of oligomer in monomers, together with jetting trajectory, drop size uniformity, and deposition accuracy of the ink‐jet inks. The chemical resistance, optical property, and mechanical property of the printed patterns depend on the oligomer structure, the arrangement of trimethoxysilane groups, and the molecular chain length. Straight lines and uniform dot arrays with excellent chemical resistance can be achieved. Dot patterns made of polymer‐silica hybrid materials and pigments remain unchanged after being immersed in γ‐butyrolactone for 200 min. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.

Fabrications and Applications of Stimulus-Responsive Polymer Films and Patterns on Surfaces: A Review

“…The rheology of jet inks can be adjusted by changing the surfactants and monomers to achieve good jetting directionality, uniform droplet size, and excellent wetting on the substrate [ 165 ]. UV-curable [ 166 , 167 ] and dual curable monomers and oligomers [ 168 , 169 ] can be used in the compositions of ink-jet fluids. Wang et al [ 170 ] reported the ink-jet printing of colloidal photonic crystal (PC) microdots that demonstrate the fastest response (about 1.2 s) to water vapor.…”

Synthesis of UV and thermal dual curing oligomer for solder resist ink using ink‐jet printing

“…To overcome this drawback, the dual curing system should be introduced. Several researches indicate that the dual‐curable oligomers show the better thermostability, higher crosslinking density, and chemical resistance, thus it is essential to synthesize a thermostable resin with excellent adhesion on solder resist ink.…”

“…Their group synthesized a kind of linear and star‐like polymer–silica hybrid oligomers and study the advantages of its hybrid curing system, presenting better thermostability by the characterization of thermogravimetric analysis (TGA). Furthermore, their group synthesized the UV and moisture polyimide oligomer chains grafting the trimethoxysilane and methacrylate segments for inkjet printing, improving the chemical resistance of the printed pattern on glass.…”

Extending microcontact printing for patterning of thick polymer layers: semi-drying of inks and contact mechanisms

“…In recent years, printing technology has attracted significant attention because patterning methods for wet materials can be an alternative to conventional fabrication processes for electronic devices while providing high throughput resulting in relatively low-cost manufacturing. Among the many printing methods available, including screen printing, inkjet printing [1], flexographic printing [2,3], gravure printing [4,5], and reverse offset printing [6][7][8], microcontact printing (µCP) is one of the most promising candidate methods for printed electronics because of its prominent capability of high-resolution patterning [9]. While µCP [10,11] was invented and developed as a chemical patterning method [12,13] in the past two decades, this technique is also attractive because of its capability to pattern various types of materials such as colloidal crystals [14,15], quantum dots [16], and catalytic colloids for electroless deposition [17].…”
