A study was conducted to demonstrate the preparation of nanosegregated amorphous composites consisting of CaCO3 and an organic polymer. These materials, exhibiting high transparency both in bulk and thin film states under mild conditions, comprise ACC (amorphous calcium carbonate) and PAA (poly(acrylic acid) that spontaneously form nanosegregated structures. The composites are capable of including a wide variety of functional molecules and nanoparticles in homogeneously dispersed states. The amorphous composites reported in this study have great potential for low-cost and green materials. The stability and transparency of the amorphous composites can be used for a wide variety of applications such as optical, biodegradable, and biofunctional materials. The transparent, stable, and crack-free thin films are also beneficial for coating of materials.
