An object has a durable superhydrophic, self-cleaning, and icephobic coating includes a substrate and a layer disposed on the substrate, the layer resulting from coating with a formulation having an effective amount of hierarchical structuring micro/nanoparticles, liquid silane having one or more groups configured to graft to a hierarchical structuring micro/nanoparticle and at least another group that results in hydrophobicity. The hierarchical structuring micro/nanoparticles are dispersed in the liquid silane. Another effective amount of synthetic adhesive, selected from thermosetting binders, moisture curing adhesives or polymers that form a strong interaction with a surface, is in solution with a solvent. Upon curing, the layer has a contact angle greater than 90 and a sliding angle of less than 10 and, less than 5% of an area of the layer is removed in a Tape test.

The present disclosure is directed to a method for potting an electrical module. In one embodiment, the method includes placing the electrical component in a potting mold, wherein the potting mold comprises an interior topology that matches a topology of one or more components of the electrical module, filling the potting mold with a potting compound and curing the potting compound over the electrical module.

Molds and method of using the molds to produce a product are provided. The molds include a first mold piece having a first wall with a first column member protruding therefrom that includes first sidewalls and a first distal end, and a second mold piece having a second wall with a second column member protruding therefrom that includes second sidewalls and a second distal end. The first and second mold pieces are configured to releasably mate to define a mold cavity therebetween and such that the first and second column members releasably mate with the first distal end being received within a cavity of the second distal end to form a seal therebetween. The mold cavity is configured to receive a product material therein and form the product therefrom. The first sidewalls and the second sidewalls are configured to define a pass through in the product.

A three-phase composite, and a preparation method and use thereof are provided. The three-phase composite includes a hollow glass microsphere composite foam and a plurality of carbon fiber tubes filled in the hollow glass microsphere composite foam; where the carbon fiber tubes are arranged in a two-dimensional closest packing manner, two adjacent carbon fiber tubes have a center-to-center spacing of 29.9 mm to 34 mm, and each of the carbon fiber tubes has a wall thickness of 0.45 mm to 1 mm; and two ends of each of the carbon fiber tubes each are sealed by an end cap.
