摘要：

Well-dispersed loads of powdered metals, metal oxides, several carbon allotropes, or nanoclays are incorporated into polyamide 6 microcapsules (PAMC) via a one-step in situ fabrication technique. It is based on activated anionic polymerization (AAP) of E-caprolactam in a hydrocarbon solvent performed in the presence of the respective micro- or nanosized loads. The forming PAMC are with controllable shape, size and load content. The results obtained show that the melt processing of PAMC is a facile method to fabricate thermoplastic hybrids with high mechanical resistance and tailored electro-magnetic characteristics. This novel concept requires low polymerization temperatures, no functionalization or compatibilization of the loads and is scalable for industrial production levels.
