Photopolymerization of ceramic/zeolite reinforced photopolymers: Towards 3D/4D printing and gas adsorption applications

Normally, 3D printed objects via photopolymerization usually don’t have fully optimized mechanical properties and functions. In this context, the addition of single filler can improve these through access to composite materials. However, inevitably has a negative influence on light penetration inside composites strongly reducing depth cure. Hence, fabrications photo-composites based combination two inorganic fillers (alumina Al2O3 zeolite LTA-5A) are reported in work. Compared pure poly(ethylene glycol) diacrylate (PEGDA) its other corresponding filler-based composites, PEGDA with 25 wt% LTA-5A Al2O3-200 had several improved properties: better cure (DOC), good (the storage modulus, tensile strength, Young’s modulus). Direct laser write (DLW) was used manufacture patterns cross-shaped resolution. Under hydrothermal stimuli, 4D printing behavior (reversible shape change) observed objects. addition, object condition ability withstand heavy stuff mass difference more than 100 times). This is first time report fabrication double (50 wt%) (ceramic zeolite) properties. Interestingly, calcinated certain structure strength CO2 adsorption performance. Therefore, work not only paves way for investigation filled multiple combinations (how keep photopolymerization), but also shows us potential applications field 3D/4D printing, microlithography functional composites.
