[0041] Preparation method of self-propelled anti-icing material

[0042] The self-propelled anti-icing material of the present invention can be made by various methods, and the specific method can be selected according to factors such as the scale and shape of the modulus pattern, and the properties of raw materials. Taking PDMS (polydimethylsiloxane) as the base material as an example, several optional methods are given below. The process of preparing patterns with other basic materials can be referred to.

[0043] Preparation Method 1: Heat Curing

[0044] This method is suitable for processing modulus patterned materials with a centimeter-scale scale, and it can also be selected for processing materials with other scales depending on the situation.

[0045] Step 1: Design a modulus pattern (such as bar, square, circle, etc.), and make a mold with detachable partition baffles according to the designed modulus pattern.

[0046] Step 2: Inject a specific proportion of PDM...

Embodiment 1

[0062] Mix the PDMS monomer and the curing agent at a ratio of 1:1 to obtain a precursor, stir evenly and place it in a vacuum oven to remove air bubbles at room temperature. Pour the precursor into a glass mold with a flat bottom, cure at 80°C for 2 hours, and demould for storage.

Embodiment 2

[0064] Mix the PDMS monomer and curing agent at a ratio of 20:1 to obtain a precursor, stir evenly and place it in a vacuum oven to remove air bubbles at room temperature. Pour the precursor into a glass mold with a flat bottom, cure at 80°C for 2 hours, and demould for storage.

Abstract

The present disclosure provides a self-propelled anti-icing material having a pattern formed by interleaving at least two materials of different moduli, with modulus spans formed at interfaces between the materials of different moduli. The present disclosure also provides methods of making self-propelled anti-icing materials. The self-propelled anti-icing material of the present disclosure can remove ice deposits with zero energy consumption under the action of ice gravity or wind force, has durable and stable anti-icing performance, and can flexibly adapt to the requirements of different application scenarios.

Description

technical field [0001] The invention relates to the technical field of functional material surfaces, and further relates to an ultra-durable self-driven anti-icing material based on modulus pattern combination. Background technique [0002] Ice deposits are inconvenient and potentially dangerous to a wide range of commercial and residential activities. Traditional deicing methods usually have low efficiency, high cost and high energy consumption, and even cause environmental pollution. Therefore, anti-icing materials have aroused the strong research interest of many scientific researchers, and promoted the rapid development of anti-icing materials. However, for aircraft, high-altitude buildings, high-voltage wires and other fields, due to the large range of deicing, or the operational difficulties involved in high-altitude operations, ordinary anti-icing / icephobic materials cannot Meet the needs. There is an urgent need for an anti-icing material that can durably and effi...
