The invention described herein generally pertains to a composition that includes a silyl-terminated polymer having silyl groups linked to a polymer backbone via triazole. The silyl-terminated polymer is a reaction product of a functionalized polymer backbone and a functionalized silane. The polymer backbone includes a first functional group, which may be one of an azide or an alkyne. The functionalized silane includes a second functional group may also be one of an azide or an alkyne, but is also different from the first functional group. The functionalized polymer backbone is reacted with the functionalized silane in the presence of a metal catalyst.

The preparation of monodispersed TiO.sub.2 nanocrystals with nanocrystal size between 1-30 nm is described herein. These TiO.sub.2 nanocrystals are used to prepare dispersions into solvents, formulation into monomers, oligomers, and polymers, and nanocomposites from the resulting formulations. Dispersions of nanocrystals can be formed in various solvents at high loading, high transmittance, and low viscosity. Formulations incorporating these nanocrystals and a matrix material are highly stable, where the resulting nanocomposites have high refractive index and are optically transparent in the visible wavelengths, with very little or no scattering.

The present invention relates to a method of preparing a hierarchically porous polymer and a hierarchically porous polymer prepared thereby. The method comprises the steps of: (a) polymerizing an external oil phase of a high internal phase emulsion (HIPE) consisting aqueous droplets to produce a cross-linked block copolymer; (b) obtaining a macroporous polymer with interconnected macropores by removing the aqueous droplets; and (c) treating the obtained porous polymer with a base, thereby obtaining a hierarchically porous polymer having three-dimensional mesopores formed in the macroporous walls. According to the method, the macropore size and mesopore size of the hierarchically porous polymer can all be controlled. The hierarchically porous polymer prepared by the method can easily separate polymers having different sizes, and thus is highly useful in the polymer separation field.

The present invention provides a method to prepare polymer materials with interlocked porous structures by freezing and demulsification, which includes: (1) Preparing an emulsion containing uncrosslinked polymers and crosslinking agents. The uncrosslinked polymers are presented in the organic phase, and the crosslinking agents are presented in the organic phase or water phase. Under freezing, the demulsification is occurred which leads to the interaction between polymers and crosslinking agents, and the crosslinked materials are obtained. (2) After removing the ice crystals, polymer materials with interlocked porous structures are synthesized. The method provided by the present invention is simple to operate, and can well adjust the porous structures of obtained porous polymer materials. In addition, it is suitable for large scale manufacturing. At the same time, this process can form different functional porous polymer materials by simply changing the used monomers. Particularly, it can prepare melt-blown fabrics with antibacterial property, high-throughput vertical porous structures and high-temperature sterilizable feature, therefore, it can be used to manufacture medical products such as masks.
