Provided is a method of treating wastewater and recovering resources in acrylic fiber production, comprising the following steps: 1) filtering wastewater from water-washing and filtering unit of acrylic fiber plants by a filter to intercept and recover high-molecular-weight polymer contained therein, and then making the recovered polymer returned back to the acrylic fiber production and entered the finished product, optionally, reusing part of filtered wastewater as low salinity water in the water-washing and filtering unit; 2) removing non-interceptable high-molecular-weight polymer in the wastewater by subjecting the wastewater to coagulation and air floatation treatment; 3) introducing the effluent into biological treatment unit and adding polyvalent metal ions as an adsorption promoter to increase the removal of the non-biodegradable organics in the biological treatment unit; and 4) removing the organics remained in the effluent from the biological treatment unit by an advanced treatment.

A process for producing a carbon sheet molding compound (SMC). An SMC manufacturing line including at least one conveyor line for laying up SMC resins on a carrier film is provided. A chopped carbon fiber which is evenly distributed using dehumidified supply air and using a pressurized air venturi apparatus which is used to debundle and randomize the carbon fibers, onto the resin on the carrier film as the carrier film moves along the conveyor.

A matrix resin composition for fiber reinforced composite materials is described. The resin is thermosetting and achieves a glass transition temperature of at least 177 C. (Tg), obtained by curing at room temperature. The matrix resin will streamline composite fabrication processes by eliminating the need for heating during the cure process. The implications of this development are significant in terms of the ease of use and elimination of procedural steps. While the resin system was developed specifically for vacuum bagging, it is expected to be viable for other composite fabrication methods including resin transfer molding (RTM) and vacuum-assisted resin transfer molding (VARTM). The resin system is viable for use with carbon fiber reinforcements to fabricate laminates at least 0.20 inches thick. The resulting laminates have low porosity and mechanical properties equivalent to those prepared with common epoxy matrix resins.

The invention relates to a method for controlling the stress distribution in a material, comprising the steps of: a, preparing a crosslinked polymer containing reversible exchange bonds; b, applying an external force to the crosslinked polymer to cause a certain strain; c, specific region of the crosslinked polymer is selectively heated while maintaining the strain. This method controls and utilizes the internal stresses which are commonly considered as unfavorable. The invention also provides a method for reading information in a polarized light field, wherein the crosslinked polymer treated by the method is transparent under natural light. The information therein can be read only under polarized light, and possesses concealment.

A method of producing a transparent polymer aerogel can include dissolving gel precursors consisting of radical polymerizable monomers and crosslinkers, radical initiators, and a chain transfer agent (CTA) in a reaction solvent, placing the gel precursors into a substrate, polymerizing the gel on the substrate, optionally removing the wet gel from the mold, optionally performing at least one solvent exchange on the gel, and drying the solvent-exchanged gel.

Disclosed are thermoset/thermoplastic composites that include a thermoset component directly or indirectly bonded to a thermoplastic component via a crosslinked binding layer between the two. The crosslinked binding layer is bonded to the thermoplastic component via epoxy linkages and is either directly or indirectly bonded to the thermoset component via epoxy linkages. The composite can be a laminate and can provide a route for addition of a thermoplastic implant to a thermoset structure.

The invention pertains to a biodegradable coating composition, comprising a crosslinked starch and a filler, and optionally a polyol plasticizer, as well as to outside structures such as greenhouses, comprising a coating layer obtained by drying the said coating composition. The invention furthermore pertains to removal of the coating layer using a targeted cleaning composition.

A wavelength conversion member, for a backlight, is provided. The wavelength conversion member includes a stack of a plurality of resin layers, with at least one of the plurality of resin layers containing quantum dots. The plurality of resin layers is integrally molded through co-extrusion, and forms a three-layer structure comprising a middle layer containing the quantum dots and upper and lower layers that do not contain the quantum dots. The upper layer and the lower layer are respectively on an upper side and a lower side of the middle layer. The upper and lower layers each contain a light scattering agent. Each of the plurality of resin layers is directly joined together with a bonding layer at an interface between the middle layer and the upper layer and not at an interface between the middle layer and the lower layer.

The present invention relates to a method for producing a three-dimensional ordered porous microstructure. In the method of the invention where the three-dimensional ordered microstructure is produced using the colloidal crystal templating process, the three-dimensional ordered microstructure thus formed is subjected to heat treatment to soften the particles, so as to effectively increase the contact between orderly arranged particles while removing the solvent used to suspend the particles. The present invention further relates to a monolithic column produced thereby. Compared to the monolithic columns produced by conventional methods, the monolithic column according to the invention is characterized in having a higher aspect ratio and a higher pore regularity, while the connecting pores in the column are relatively large in pore size.
