In this study, calcite and zeolite minerals, with well-known incombustibility properties, were used together with huntite hydromagnesite as auxiliary minerals to obtain better mechanical properties. In this context, a synergistic effect was created by adding zeolite and calcite to polymer composite systems containing huntite hydromagnesite, and flame retardant polypropylene matrix composites were produced using a twin screw extruder.

In this study, we synthesized hydroxyapatite (HA) on polyvinyl alcohol/TiO2 (PVA/TiO2) in which TiO2 was prepared by the sol-gel method. HA was formed by immersing the membrane in the simulated body fluid (SBF) solution. We improved the mechanical strength of the membranes by adding glutaraldehyde (GA) combining with heat treatment to cross-link the polymer network.

This work aimed to introduce nanosized SiO2 into the CS matrix to produce three-dimensional (3D) scaffolds by solvent casting combined with salt leaching using NaCl as a porogen agent. The amount of the porogen to polymer was varied to produce 3D CS/SiO2 scaffolds with suitable pore sizes and porosity.

In the present study, we have made an attempt to prepare complexed PVA-PVP-KNO3-BaTiO3 blend composite polymer electrolyte membranes composed of potassium nitrate (KNO3) as salt and BaTiO3 of various concentrations as filler and studied their properties. The advantages of addition the fillers are the increase in ionic conductivity at room temperatures and the improvement of the stability at the interface with electrodes.

The curing agent content plays an important role in the synthesis of polymer composites, as it determines the quality and durability of these materials. Cyanethyl-diethylenetriamine (CEDETA) was used as the curing agent for epoxy epikote 828. The effect of CEDETA content on the gel content and fracture toughness (KIC) of epoxy resin, as well as the effect of reinforcing fabric on the mechanical properties of composite materials was studied.

Ebook "Fillers for polymer applications" is a transition from what was originally a series of contributions for an Encyclopedia. Most of the chapters are thus rather short with their main aim being to give a good overview of the topic and point the reader to the best of the detailed literature. Something also needs to be said about the literature referenced. Filler technology is very much industry, rather than academic, based.
