A solvent resistant, transparent aromatic polyamide film with a high refractive index may be made by reacting at least one aromatic diacid chloride, a first aromatic diamine, and at least one crosslinking agent or a second aromatic diamine in an organic solvent to form an aromatic polyamide polymer in solution. In one embodiment, the at least one aromatic diacid chloride is selected from the group consisting of isophthaloyl dichloride, terephthaloyl dichloride, 2, 6- naphthalene-dicarboxylic chloride, or combinations thereof and the first aromatic diamine is selected from the group consisting of 9, 9-Bis(4-hydroxyphenyl)fluorine, 2, 2 ,5,5- Tetrachlorobenzidine, or combinations thereof. The organic solvent is then evaporated from the aromatic polyamide polymer in solution to form a transparent aromatic polyamide precursor film. The precursor film is then heated at a temperature close to the glass transition temperature of the transparent aromatic polyamide precursor film to form the solvent resistant, transparent aromatic polyamide film.

A structure comprises a plurality of spherical triangular units (100, 200, 300) on a plurality of levels. The plurality of spherical triangular units (100, 200) on one level of the plurality of levels are essentially identical to each other and are essentially equally spaced radially relative to a center of a sphere (10). Each of the plurality of spherical triangular units (100, 200, 300) comprises three planar panels (110, 120, 130, 210, 220, 230, 310, 320, 330), each with an end surface (101, 102, 103, 201, 202, 203, 301, 302, 303) comprising a minor arc of a great circle of the sphere (10). A spherical triangular unit (300) on a level above the first level of the structure is configured to be joined with two neighboring spherical triangular units (100, 200) on the level below. The structure is substantially a dome. The structure has a superior ability to survive disasters such as tornadoes, hurricanes, earthquakes etc. The above structure is cost-efficient, energy efficient, extremely durable and easily maintained.


The present invention provides a method for preparing graphene by using a molten inorganic salt reaction bed. The method includes the following steps: using phthalocyanine substance as a reaction raw material, well-mixing an inorganic salt with the phthalocyanine substance in the inorganic salt reaction bed, performing pyrolysis by using a temperature programmed method in an atmosphere furnace under a protective gas, and separating out a highly planar-oriented graphene material. By adopting the method, a graphene material can be obtained by pyrolysis in a non-hydrogen environment. The method is simple, the process is environmentally friendly, industrial production can be achieved, and the obtained graphene is highly planar-oriented.


A locking apparatus, a vehicle safety belt adjustment apparatus, and a vehicle safety belt. The locking apparatus used for controlling a movable chain, strip or strap-shaped object (71) comprises a support frame; a roll shaft (6) with a friction surface or a sprocket pitch slot (64), the roll shaft (6) being fixedly connected to a support rod (66), and one end of the support rod (66) being pivotally connected onto the support frame; a pawl (62) disposed above the roll shaft (6) and capable of rotating around one end; and a pressurization body (3) opposite to the roll shaft (6) along a transverse direction, thereby forming a roll gap between the roll shaft (6) and the pressurization body (3). The roll shaft (6) can freely rotate when the roll shaft (6) is in a middle state. When the roll shaft (6) is forced to downwards pivot until a ratchet disposed on a contact base (65) engages with a ratchet (6302) of the roll shaft (6) to prevent the rotation of the roll shaft (6), the object (71) can be locked. When the roll shaft (6) is forced to upwards pivot until the ratchet (6302) of the roll shaft (6) abuts against the pawl (62), the roll shaft (6) can still rotate; when the object (71) changes the direction to downwards move, the pawl (62) engages with the ratchet (6302) of the roll shaft (6) to prevent the rotation of the roll shaft (6) and loses the engagement with the ratchet (6302) of the roll shaft (6) as the roll shaft (6) downwards pivots. The pressurization body (3) may comprise a pair of swing rods which have one ends hinge-connected with each other and can be bent.
