Provided are an LCP film and a laminate comprising the same. The LCP film is made of an LCP resin comprising a structural unit represented by Formula (1): -L-Ar-L- (1), wherein -L- and -L- are respectively —O— or —CO—; —Ar— is an arylene group. Formula (1) comprises structural units Based on a total molar number of the structural unit represented by Formula (1), a molar number of the structural unit represented by Formula (I) is in the range from 15 mole % to mole %, and a sum of molar numbers of the structural units represented by Formulae (I) and (II) is in the range from 80 mole % to 100 mole %. The LCP film has a thickness and a transmittance, wherein when values of the thickness (in μm) and the transmittance are put into Formula (III), the obtained value is from 0.055 to 0.090. Formula (III): Log(1/TT %)/(Thickness).

Provided are a liquid crystal polymer film (LCP film) and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and the first surface has an arithmetical mean height of a surface (Sa) less than 0.32 μm. The LCP film with proper Sa is suitable to be stacked with a metal foil, such that a laminate comprising the LCP film can have an advantage of low insertion loss.

Provided are hard carbon beads, their preparation method, and an energy storage device comprising the same. Microwave heating is used to synthesize cross-linked phenolic formaldehyde for reducing energy consumption and controlling the crosslinking density of cured phenolic formaldehyde. The problems caused by high temperature heating and hydrothermal process for curing resin can be solved by the instant disclosure, which can increase the economic values of electrode and energy storage device comprising the hard carbon beads.

Hard carbon beads, their preparation, and energy storage device comprising the same

Provided are a laminate, a circuit board, and a liquid crystal polymer (LCP) film comprised therein. The laminate comprises a metal foil and an LCP film. The LCP film in the laminate has a dissipation factor before water absorption (Df'), a dissipation factor after water absorption (Df&#x2032;), and a relative percentage difference between dissipation factors (&#x394;Df&#x2032;), which is calculated by the following equation: wherein &#x394;Df&#x2032; may be less than or equal to 16%. By controlling &#x394;Df&#x2032; of the LCP film in the laminate, the insertion loss of a circuit board comprising a laminate during signal transmission in low-, medium-, and/or high-frequency bands is decreased and/or inhibited. In addition, the difference between the insertion losses of signal transmission before and after water absorption is decreased, so the laminate is suitable for high-end or outdoor high-frequency electronic products.
