The present disclosure provides a display motherboard and a method for manufacturing the same, a display substrate and a method for manufacturing the same, and a display device, and belongs to the field of display technology. In the method for manufacturing the display motherboard of the present disclosure, the display motherboard includes a plurality of display substrate areas each including a sub display area and a sub bending area; and the method for manufacturing the display motherboard includes: forming an adhesive force variable back film material having a first adhesive force on a flexible underlying substrate; removing the back film material in positions above the sub bending areas; and treating the remaining back film material to form a back film having a second adhesive force, wherein the second adhesive force is greater than the first adhesive force.

A nonaqueous electrolyte secondary battery separator, which includes a porous film containing a polyolefin-based resin as a main component, has a difference of not more than 2.5 between (a) a white index measured on a surface of the porous film which has not been irradiated with ultraviolet light having 255 W/m.sup.2 and (b) a white index measured on the surface of the porous film which has been irradiated, for 75 hours, with the ultraviolet light having 255 W/m.sup.2.

A paint roller manufacturing system and method are described. In an embodiment, an inner strip of material and an outer strip of material are wound about a mandrel in offset relation. The inner strip of material and the outer strip of material each comprise material that results in a final paint roller which shrinks by less than 2.5 percent of the final paint roller axial length, or which has shrinkage that varies by less +/0.1%, upon hardening and setting. An adhesive is applied to at least a portion of the outer strip as it is wound about the mandrel. A length of fabric is wound about at least the outer strip to form a paint roller tube, and compression is applied to the paint roller tube while advancing the paint roller tube in a direction parallel to the mandrel. A precision measuring or sensing device is used to control a cutting device causing the cutting device to cut the advancing paint roller tube into pre-selected lengths prior to the paint roller tube hardening and setting.

The embodiment relates to a balanced propeller and to an extrudable metal polymer composite and process for making and using the composite to make balancing weight strips for marine or boat propellers. Metal particulate of adequate particle size is mixed with a polymer that is extruded or injection molded to form a high-density weighted strip.

A composite membrane, a biosensor, and preparation methods thereof are disclosed. In the preparation process, a moldable and plastic material is used as a carrier; after a dispersion liquid of a nanocarbon material wets the carrier, by means of multiple stretching and folding processes, the nanocarbon material is uniformly distributed and arranged regularly inside the entire plastic material in a stretching strain direction. The prepared composite membrane is elastic, attachable, and cost-efficient, and may detect strains as high as 530%. The composite membrane further has high sensitivity and high durability, and may be effectively applied to a biosensor for monitoring motion and humidity.

The invention generally relates to shape memory films that are tri-functionally crosslinked and that comprise multiple, non-terminal, phenylethynyl moieties. In addition, the present invention relates methods of fabricating such films. Due to the improved properties of such SMPS, the SMP designer can program in to the SMP mechanical property enhancements that make the SMP suitable, among other things, for advanced sensors, high temperature actuators, responder matrix materials and heat responsive packaging.

Inverse origami design for soft robotic development is described herein. A method as described herein can include determining, by a system comprising a processor, shape parameters corresponding to an input shape; generating, by the system based on the shape parameters, an origami crease pattern representative of the input shape, wherein the origami crease pattern comprises respective origami cell units, and wherein the origami crease pattern is defined by a group of vector size parameters corresponding to relative fold lengths associated with the respective origami cell units, a vector angle parameter corresponding to fold angles associated with the respective origami cell units, and a scalar cell height parameter; and imprinting, by the system, the origami crease pattern onto a tangible medium.

The invention generally relates to shape memory films that are tri-functionally crosslinked and that comprise multiple, non-terminal, phenylethynyl moieties. In addition, the present invention relates methods of fabricating such films. Due to the improved properties of such SMPs, the SMP designer can program in to the SMP thermomechanical property enhancements that make the SMP suitable, among other things, for advanced sensors, high temperature actuators, responder matrix materials and heat responsive packaging.

A system and method of constructing a 4D-printed ceramic object includes extruding inks including particles and polymeric ceramic precursors through a nozzle to deposit the inks on a heating plate, whereby a 3D-printed elastomeric object is formed on the heating plate, folding the 3D-printed elastomeric object into a complex structure to form a 4D-printed pre-strained elastomeric object, and converting the 4D-printed elastomeric object into the 4D-printed ceramic object.
