A microcellular thermoplastic polyurethane foamed sheet with a high foaming ratio includes components of: TPU with 70100 parts by weight, and polydimethylsiloxane with 030 parts by weight. The present disclosure has the following advantages: because the supercritical fluid has a relatively high solubility in the polydimethylsiloxane while the polydimethylsiloxane has a relatively low interfacial tension, mixing a small amount of polydimethylsiloxane into the TPU significantly facilitates the diffusion speed of the supercritical fluid in the TPU and shortens the diffusion equilibrium time of the supercritical fluid in the TPU. In addition, a method of manufacturing a microcellular thermoplastic polyurethane foamed sheet with a high foaming ratio is further provided.

A method for manufacturing a composite semipermeable membrane is capable of forming, on a surface of a porous support in a highly reproducible manner, a separation layer that is extremely thin and that exhibits superior separability. It provides, on a surface of a porous support, a composite semipermeable membrane that has an organic/inorganic hybrid separation layer that is extremely thin and that exhibits superior separability. A method for manufacturing a composite semipermeable membrane includes forming, on a surface of a porous support, a separation layer containing a cross-linked condensate having a siloxane bond by bringing an organic solution that contains an organic silicon compound containing three or more reactive functional groups, each of which is at least one type selected from a hydrolyzable group and a hydroxyl group, into contact with water or an aqueous solution on the porous support, and by performing interfacial polycondensation of the organic silicon compound.

This invention provides a scrollable and foldable transparent polysiloxane film and its preparation and self-healing method. 2-Hydroxyethyl disulfide, diisocyanate and alkane chloride were mixed and reacted to get disulfide-containing diisocyanate. ,-Aminopropyl terminated polydimethylsiloxane, diisocyanate and alkane chloride were mixed and reacted get linear chain-extended polydimethylsiloxane. Linear chain-extended polydimethylsiloxane, multi-amino terminated hyperbranched polysiloxane, disulfide-containing diisocyanate and alkane chloride were mixed and poured into a mould. After drying, the scrollable and foldable transparent polysiloxane film was obtained. The polysiloxane film described in this invention are constructed by dynamic physical crosslinking induced by hydrogen bond and permanent chemical crosslinking generated by hyperbranched polysiloxane. Hence, the polysiloxane film achieves both high stiffness and toughness. The good self-healing behavior of the polysiloxane films is originated from the temperature controlled dissociation of hydrogen bonds and exchange reaction rate of disulfide bonds.

Urea and amine comprising sol-gel hybrid coatings have been developed for numerous applications, including capillary microextraction-high performance liquid chromatographic analysis from aqueous samples. A fused silica capillary may be coated from the inside with surface bonded coating material and may be created by in-situ sol-gel reaction(s). Urea-functionalized coatings can be immobilized on the inner surface of a capillary by condensing silanol groups of capillary and sol-solution. Urea functionalized, sol-gel coated capillaries may be installed, e.g., in HPLC manual injection ports, and optionally pre-concentrated analytes including phenols, ketones, aldehydes, and/or polyaromatic hydrocarbons, from highly polar to non-polar, maybe analyzed by online extraction and high-performance liquid chromatographic. Such coatings may achieve sensitivities with lower detection limits (S/N=3) of 0.10 ng/mL to 14.29 ng/mL, with reproducibilities of <12.0% RSD (n=3), or <10.0% RSD (n=3) by exchanging the capillary of the same size.
