有機/無機紫外光固化材料合成及研究

透過光敏化的機制讓聚醯胺酸能快速固化有利於工業用途，而光起始的來源是透過聚醯胺酸本身的發光機團再加上額外的光起始劑作輔助，來達到快速固化的目標。透過聚醯胺酸的末端接枝，來形成以壓克力機團結尾的寡聚物，並額外加入不同種類的反應性單體(含有壓克力機團)，透過上述的光敏化反應使系統呈現自由基的聚合，令壓克力機團形成交聯網絡，使固化的目的快速達成。壓克力機團與聚醯胺酸主體之間的連接是透過矽氧烷的sol-gel反應生成，而矽氧烷的－OH基團對於金屬基材有很好的密著。添加的反應性單體對黏著性也有幫助。實驗中得知，改變塗料厚度到一定程度及添加不同種類的反應性壓克力單體(交聯)都會影響光固化速度及固化後塗料黏性及硬度，所選用的稀釋劑以BPA10EODA最有效果。

Through mere mechanism of photosensitive, is it gather poly(amic acid) can fast curing favorable to the industrial use to let, and photoinitial source through gather poly(amic acid) sour one's own luminescence group in addition, extra mere photoinitiate is it assist to make only, to reach the goal of fast curing. Connect one through gathering the sour end of poly(amic acid), to form it with the oligomer of the ending of the acrylate group and extra to join different types of monomer(contain acrylate group), React through the above -mentioned mere ptotosensitization make system appear free radical polymerization let acrylate group form network. The connection of Acrylae group and poly(amic acid) are to react and produce through sol-gel of silane, and it is dense that silane one - OH group has the very good adhesion to the metal substrate. Monomer added is helpful too to the adhesive. Learn in the experiment, change the thickness of coating to certain extent and add different types of acrylate monomer Will influence the curing speed, the hardness and adhesive after curing, the monomer selected for use have a result most with BPA10EODA.
