High-strength boehmite-acrylate composites for 3D printing: Reinforced filler-matrix interactions.

The development of additive manufacturing has offered great potential as well as challenge to resins with good performance. Here we report a facile strategy to obtain significant enhancement of mechanical properties for resins via incorporation of boehmite nanowires surface modified by a new modifier β -carboxyethyl acrylate ( β -CEA), instead of the commonly used coupling agent 3-trimethoxysilylpropyl methacrylate (TMSPM). Fourier Transform Infrared Spectroscopy (FT-IR) and thermogravimetric analysis (TGA) characterizations were conducted to demonstrate the grafting of β -CEA onto the surface of boehmite nanowires. Significant mechanical enhancement was demonstrated by manufacturing and evaluation of product quality of delicate Fullerene model with neat acrylate and composite resins with β -CEA-AlOOH via Digital Light Processing (DLP) 3D printing.
