Synthesis and Characterization of Photoresponsive Polyacrylates for Pressure Sensitive Adhesives Application

Abstract Details

2015, Master of Science, University of Akron, Polymer Science.
Stimuli responsive polymeric materials can adapt to surrounding environments which may be sensitive to various factors, such as temperature, electric field, magnetic field, pH or light. Photoresponsive polymers are particularly interesting since light can be controlled spatially and temporally, which makes them potentially useful in many applications such as shape memory materials, surface patterned materials and controlled drug release. Switchable adhesion exhibits the ability to trigger adhesion in response to environmental changes, for example, temperature, light, pH, solvent, mechanics, and electro or magnetic field. The noteworthy functionality of switchable adhesives has been met with significant interest in many fields of material science and engineering and can find many useful and valuable applications, including the pain-free removal for wound dressing, simplification of separation for material recycle and easily repair or replacement of components in electronics. In this work, photoresonsive properties are utilized for switchable adhesion, which allows the debonding on demand. A series of novel photoresponsive polyacrylates are designed and synthesized, which are copolymers of n-butyl acrylate, 2-carboxyethyl acrylate and chromophores-contained diacrylate cross-linker. The photoresponsive cross-linker was introduced to achieve the removal of the adhesives since the photoresponsive linkage can be cleaved upon photo-irradiation. Besides, these polymers were synthesized by emulsion polymerization, which is environmental-friendly and also facilitates their industrial applications for pressure sensitive adhesives (PSAs) products.
