“…As being used in many ways, modifying polyamides to improve the properties is necessary . In recent years, organic–inorganic composites especially the composites interface between inorganic particles and based polymer have gained much attention for their versatility by changing the inorganic materials and based polymer . And nanoscale particles are without doubt one of the most outstanding fillers added in the polymer for their high specific surface area, low density, and high Young's modulus.…”

The polyamide-6 materials were mixed with nano-silica modified by c-glycidoxypropyltrimethoxysilane (GPS) via a melt blending process. The idea was to study the correlation between content of GPS and PA6/silica interfacial interactions as well as mechanical properties of PA6/silica composites. The epoxy groups in GPS could react with -COOH and -NH 2 in PA6 to produce the covalent bond and hydrogen bonding based on FTIR chart, TG analysis, and TEM analysis results. The DSC results show that nanosilica could encourage the formation of the hydrogen bonded structure of the a-PA6 crystals. However, the over GPS could confine the motion of polyamide-6 and decrease the generation of a-PA6 crystals resulted the decrease of mechanical properties. So the amount of epoxy groups grafted on nano-silica has a threshold effect on strength of PA6. POLYM. COMPOS., 35:435-440, 2014.

“…Damping materials are widely used in the field of vibration reduction and noise control by means of converting the mechanical energy into the heat and dissipating it [1]. Damping materials are generally classified into four categories: a) Viscoelastic damping materials, b) piezoelectric damping composites; c) high damping alloy materials; and d) intelligent damping materials [2].…”

In this study, a new type of piezoelectric damping composites was prepared by embedding thin plates of piezoelectric ceramic (Pb (Zr x T 1−x ) O 3 , PZT ) with various sizes in epoxy resin matrix. An external electric resistor was connected to the piezoelectric plates of the composites to improve the damping behaviors of the composite structure. Dynamic Mechanical Analyzer (DMA8000 manufactured by Perkin Elmer) was used to study the PZT/epoxy piezoelectric composite system at different temperature and frequency range. The experimental results were discussed in terms of the damping and viscoelastic effect of the PZT-epoxy composite system.

“…3 According to the theory of piezoelectric shunt damping, adding an appropriate piezoelectric component and a conductive phase to damping materials can be advantageous for energy dissipation. [3][4][5][6] A number of composites with metals, 7 carbon black (CB), [8][9][10][11][12] carbon bers, [13][14][15][16] carbon nanotubes, [17][18][19][20][21] and graphene as the conductive phase have been prepared and investigated. However, to achieve the conductive percolation threshold, a lot of the conductive phase needs to be added, which may affect the performance of the matrix.…”
