A degradable polymeric nanotube (NT) dispersant comprises a multiplicity of NT associative groups that are connected to a polymer backbone by a linking group where there are cleavable groups within the polymer backbone and/or the linking groups such that on a directed change of conditions, bond breaking of the cleavable groups results in residues from the degradable polymeric NT dispersant in a manner where the associative groups are uncoupled from other associative groups, rendering the associative groups monomelic in nature. The degradable polymeric nanotube (NT) dispersant can be combined with carbon NTs to form a NT dispersion that can be deposited to form a NT film, or other structure, by air brushing, electrostatic spraying, ultrasonic spraying, ink-jet printing, roll-to-roll coating, or dip coating. The deposition can render a NT film that is of a uniform thickness or is patterned with various thicknesses. Upon deposition of the film, the degradable polymeric nanotube (NT) dispersant can be cleaved and the cleavage residues removed from the film to yield a film where contact between NTs is unencumbered by dispersants, resulting in highly conductive NT films.
可降解聚合物纳米管(NT)分散剂包括多个NT关联基团,这些基团通过连接基团连接到聚合物骨架,其中聚合物骨架和/或连接基团中有可断裂的基团,因此在指定条件的变化下,可断裂基团的键断裂会导致可降解聚合物NT分散剂的残留物以一种方式分散,其中关联基团与其他关联基团解耦,使关联基团具有单体性质。可降解聚合物纳米管(NT)分散剂可以与碳NT结合形成NT分散液,可以通过喷雾、静电喷涂、超声波喷涂、喷墨印刷、卷对卷涂覆或浸涂沉积形成NT薄膜或其他结构。沉积可以使NT薄膜具有均匀的厚度或具有不同厚度的图案。在薄膜沉积后,可降解聚合物纳米管(NT)分散剂可以被断裂并从薄膜中移除,以产生接触NT的膜,该膜不受分散剂的阻碍,从而产生高导电性NT薄膜。
