To develop an adhesion system satisfying both constant adhesion strength during use and quick debonding ability during a dismantling process. Adhesive properties were investigated for the random and block copolymers consisting of 1-isobutoxyethyl acrylate (iBEA), 2-ethylhexyl acrylate (2EHA), and 2-hydroxyethyl acrylate (HEA) as the dismantlable pressure-sensitive adhesives in the presence of a photoacid generator in response to dual external stimuli of photoirradiation and post baking. The use of LED combined with a new photoacid generator SIN-11 was enable us to achieve a rapid dismantling process during UV irradiation within several minutes. The protection of the ester alkyl group in the iBEA repeating unit to give an acrylic acid unit was suppressed by the introduction of isobornyl acrylate (IBoA) as the additional unit into the copolymer of iBEA, 2EHA, and HEA. While IBoA‐containing block copolymer showed a constant adhesive strength during photoirradiation as the single external stimulus, deprotection was immediately induced by the subsequent heating, leading to a significant decrease in the adhesive strength. The copolymer including the iBEA and IBoA units was revealed to function as the highly sensitive adhesive materials for dual-locked dismantlable adhesion.

响应于可分解粘附的双重刺激，控制含1-异丁氧基乙基和异冰片酯的丙烯酸酯聚合物的粘附强度

为了开发一种既能在使用过程中保持恒定的粘合强度又能在拆卸过程中满足快速脱粘能力的粘合体系。在光酸产生剂的存在下，研究了由丙烯酸1-异丁氧基乙酯（iBEA），丙烯酸2-乙基己酯（2EHA）和丙烯酸2-羟乙酯（HEA）组成的无规嵌段共聚物的粘合性能。响应光辐照和烘烤后的双重外部刺激。将LED与新型光酸产生剂SIN-11结合使用，使我们能够在几分钟内在紫外线照射下实现快速拆卸过程。通过将丙烯酸异冰片酯（IBoA）作为附加单元引入iBEA，2EHA和HEA的共聚物中，抑制了iBEA重复单元中酯烷基对丙烯酸单元的保护。尽管含IBoA的嵌段共聚物在光辐照过程中显示出恒定的粘合强度，这是单一的外部刺激，但随后的加热会立即引起脱保护作用，从而导致粘合强度显着降低。揭示了包括iBEA和IBoA单元的共聚物起着高灵敏度的粘合材料的作用，用于双锁可拆解粘合。导致粘合强度显着降低。揭示了包括iBEA和IBoA单元的共聚物起着高灵敏度的粘合材料的作用，用于双锁可拆解粘合。导致粘合强度显着降低。揭示了包括iBEA和IBoA单元的共聚物起着高灵敏度的粘合材料的作用，用于双锁可拆解粘合。
