    • The invention pertains to a method of obtaining a pair of substrates spaced from each other by spacers comprising: a) providing a first substrate overlaid with a first layer with a patterned hydrophobic second layer or a patterned hydrophilic second layer that can take on an electrostatic charge; and b) optionally treating the parts of the first layer that are not covered with the hydrophobic or hydrophilic second layer to form a patterned hydrophilic third layer that can take on an electrostatic charge with a sign that is opposite to the sign of the electrostatic charge that can be taken on by the hydrophilic second layer, if the second layer is a hydrophilic layer; c) providing at least one of the first, second, and third layer with an electrostatic charge; d) contacting the electrostatically charged patterned first substrate with a dispersion of polymeric particles (spacers), which are functionalized so that the polymeric particles at their surface can take on an electrostatic charge with a sign opposite to the sign of the electrostatic charge of the at least one of the first, second, and third layer, to electrostatically bond the polymeric particles to the layer provided with an electrostatic charge having a sign that is opposite to the sign of the electrostatic charge of the polymeric particles; e) optionally removing the functionalized polymeric particles from parts to which the functionalized polymeric particles are not electrostatically bonded, and/or the hydrophobic or hydrophilic second layer, if the polymeric particles are not electrostatically bonded thereto; and f) thereafter connecting the first substrate to a second substrate to give the pair of substrates.
    • 本发明涉及通过间隔件获得彼此间隔开的一对基板的方法,该方法包括:a)提供覆盖有第一层的第一衬底,该第一衬底具有构图的疏水性第二层或图案化的亲水性第二层,其可以承受静电电荷 ; 和b)任选地处理未被疏水或亲水的第二层覆盖的第一层的部分以形成图案化的亲水性第三层,其可以以与静电电荷符号相反的符号进行静电电荷, 如果第二层是亲水层,则可以被亲水性第二层吸收; c)提供第一,第二和第三层中的至少一个静电荷; d)使带静电的图案化的第一基板与聚合物颗粒(间隔物)的分散体接触,聚合物颗粒(间隔物)的分散体被官能化,使得其表面处的聚合物颗粒可以带有相反于带有静电荷的符号的符号的静电电荷 第一层,第二层和第三层中的至少一个,将聚合物颗粒静电地粘合到具有静电电荷的层上,该静电电荷具有与聚合物颗粒的静电电荷的符号相反的符号; e)如果聚合物颗粒未静电键合到其上,则任选地从官能化聚合物颗粒不静电键合的部分除去官能化的聚合物颗粒,和/或疏水或亲水的第二层; 以及f)此后将第一衬底连接到第二衬底以产生一对衬底。
