Reinforcing Epoxy Resin with Polydopamine-Coated Al(OH)₃: A Biomimetic Method to Constructing Organic-Inorganic Hybrid Materials

Abstract:

A facile biomimetic method was developed to enhance the interfacial interaction in organic-inorganic hybrid materials. By mimicking mussel adhesive proteins, a monolayer of polydopamine (PD) was constructed on surface of Al (OH)₃ particles through a controllable coating pathway. The modified Al (OH)₃ (PD-Al (OH)₃) was incorporated into an epoxy resin. It is found that the strong interfacial interactions brought by the polydopamine benefits the effective interfacial stress transfer, leading to greatly improved flexural properties of the organic-inorganic hybrid resin.
