电喷雾沉积（ESD）是一种涂层技术，其中溶液通过带电毛细管，使溶液通过一系列库仑裂变分散成子液滴，直到液滴到达接地目标。这种方法是有利的，因为它能够用某些溶液产生纳米结构的自限制电喷雾沉积（SLED）涂层。一个很大的缺点是它使用大量的溶剂。这是浪费的，并且导致喷雾花费很长时间来存款膜。为了缓解这一问题，本研究的重点是喷涂单体，其可以以比其相应的聚合物高得多的重量百分比喷涂，在紫外光下与光活化聚合剂和交联剂共混以产生聚合物中喷。发现使用甲基丙烯酸甲酯作为单体的喷雾沉积了由可以任选交联的低聚聚合物组成的膜。
Electrospray deposition (ESD) is a coating technique in which a solution is passed through a charged capillary, causing the solution to disperse into child droplets through a series of Coulomb fissions until the droplets reach a grounded target. This process is advantageous due to its ability to createnanostructured self-limiting electrospray deposition (SLED) coatings with certain solutions. A large disadvantage is its use of a large amount of solvent. This is wasteful and causes sprays to take a long time to deposit a film. To alleviate this, this study focuses on spraying monomers, which can be sprayed at a much higher weight percentage than their corresponding polymers, blended with a photoactivated polymerizing agent and crosslinker under ultraviolet light to create polymers mid-spray. It was found that the spray, using methyl methacrylate as the monomer, deposited a film consisting of oligomeric polymers that could be optionally crosslinked.
