主 题:Hot melt adhesive Polyamide-amine Reusability Cultural relics restoration
摘 要:The development of adhesive technology is gaining increasing attention in machinery,electronics,aviation,and other ***,traditional adhesives are difficult to be peeled and removed after cross-linking and curing due to the limited solubility in common solvents,which causes pollution and damage to the surface of the *** this work,we synthesized random hyperbranched polyamide-amine hot melt adhesives through Michael addition of 1,8-octanediamine and N,N’-methylene diacrylamide(ODA-RHP HMA).Owing to the presence of various polar groups,ODA-RHP HMA exhibited robust lap shear strength to different substrates,including glass(6.6 MPa),ceramics(10.3 MPa),steel(11.5 MPa),and aluminum(11.8 MPa).Due to the hydrogen bonds in ODA-RHP,the HMA demonstrated intrinsic self-healing ability,which can be used repeatedly when being subjected to cyclic heating and *** ODA-RHP HMA can be swollen or dissolved in ethanol,the adhesives can be easily removed through *** addition,ODA-RHP exhibited aggregation-induced luminescence due to the tertiary amine structure in the molecular structure of ODA-RHP,which can be used in the field of cultural relics restoration.
