摘要
为了减小纳米压印光刻胶与模板间的接触黏附力,合成了一种无氟抗粘巯基一烯纳米压印光刻胶。以A,A,A’-三(4-羟苯基)-1-乙基-4-异丙苯(TPA)和溴丙烯为原料,采用相转移催化法制备了一种功能性单体A,A,A’-三(4-丙烯基苯基醚)-1-乙基-4-异丙苯(TPAE),并将其按特定配比与三羟甲基丙烷三(3-巯基丙酸酯)和光引发剂配制成纳米压印光刻胶。实时傅里叶红外光谱(FT-IR)分析表明,当辐射剂量为200mJ/cm^2时,双键的转化率为78.0%,巯基的转化率为78.1%。胶膜的去离子水接触角为90°。纳米压印光刻胶脱模后的图形结构规整,保真度高,具有良好的脱模性能。
In order to reduce the contact adhesion between the nanoimprint lithography resist and mold, a "thiol-ene" nanoimprint lithography resist with fluorine-free anti-sticking property was synthesized. A functional monomer A, A, Ar-tris (4-propenenylphenyl ether) -1-ethyl-4-iso- propylbenzene (TPAE) was synthesized with the phase-transfer catalysis method using A, A, Ar-tris (4-hydroxyphenyl) -1-ethyl-4-isopropylbenzene (TPA) and allyl bromide as raw mate- rials. The nanoimprint lithography resist was obtained via mixing TPAE, trimethylolpropane tris (3-mercaptopropionate) and photoinitiator with specific proportion. The real-time Fourier trans- form infrared spectroscopy (FT-IR) analysis shows that with an irradiation dose of 200 mJ/cm2 , the double bond conversion rate and thiol conversion rate are 78.0% and 78.1%, respectively. The deionized water contact angle of the resist film surface is 90°. The nanoimprint lithography resist after demolding has a regular pattern structure, high fidelity and outstanding demolding property.
