摘要:
An epoxy resin containing side-chain-tethered caged POSS and a preparation method thereof as well as epoxy resin material containing POSS-epoxy and a preparation method thereof are disclosed. The epoxy resin containing side-chain-tethered caged POSS (POSS epoxy) is formed by tethering of POSS group to the side chain of the diglycidyl ether of bisphenol A (DGEBA) epoxy resin. The preparation method of the POSS epoxy includes a step of reacting epoxy resin with caged POSS to form epoxy resin containing side-chain-tethered caged POSS (POSS-epoxy). The preparation method of epoxy resin material containing POSS-epoxy includes a step of reacting DGEBA epoxy resin with POSS-epoxy to get epoxy resin material containing POSS-epoxy. The POSS-epoxy is distributed evenly in the epoxy resin material with POSS-epoxy.

The invention provides a polymer/carbon nanotube composite film with high gas permeability resistance and manufacturing method thereof. The manufacturing method uses the in-situ polymerization method to form a polyaniline polymer composite material with multi-layer carbon nanotubes. Then, the polyaniline polymer composite material is under a heat reflux modification to form a charge transferring compound, so that the multi-layer carbon nanotubes will be distributed in a polyaniline polymer substrate uniformly and dispersively, and the gas permeability resistance of the polymer/carbon nanotube composite film can be largely improved.

摘要:
A phenolic resin that increases its toughness by polydimethylsiloxane and a process of preparing the same is provided. Polydimethylsiloxane is added as a coupling agent in a γ-glycidoxypropyltrimethoxysilane-modified phenolic resin to improve the compatibility between polydimethylsiloxane and the phenolic resin. Then, tetraethoxysilane is added to conduct hydrolysis condensation and obtain tougher and thermally stable phenolic resin.

A waterproof racket includes an annular skeleton, a receiving pocket having a pocket cavity, and a trampoline layer affixed to the receiving pocket. The annular skeleton is received in the pocket cavity to retain the receiving pocket in an annular configuration. The trampoline layer is affixed to a centerline of the receiving pocket, wherein the trampoline layer is stretched to form a trampoline surface in a tension manner.
