Problems solved by technology

[0002] Liquid flavors have the characteristics of multiple components, and the volatilization characteristics of each component are different, which leads to the quick volatilization of the head fragrance in the natural state of the liquid flavor. After a long time of use, the quality of the flavor is not complete, and the odor components are missing, which greatly reduces the use time of the flavor.
A single component or structure is often limited to liquid storage or odor permeation for liquid flavors, and the controllable release cannot achieve the desired effect, and cannot effectively prolong the service life of liquid flavors

Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to a high polymer material with a controllable smell releasing function and a preparation method of thehigh polymer material. The material has a multilayered structure, and has functions of essence storage, slow releasing, controllable releasing and the like. The inner layer of the material is an essence storage layer, is a high polymer porous material, and can efficiently adsorb and store liquid essence; the middle layer is an essence slow releasing layer, is a fluorine-containing high polymer nano fiber layer, and has functions of preventing the liquid essence from spilling out, providing a smell penetrating channel and the like; and an outer layer is a micro-nano-structured porous high polymer material layer, and has a controllable odor releasing function. The prepared material is suitable for various liquid essences, selective adsorption or chemical reaction of various layers of materials to chemical components in the essence do not exist, the material can have functions of smell storing, slow releasing, controlled releasing and the like of various liquid essences, and has wide application prospect in the field of odor releasing, and a reliable, adjustable and controllable solution is provided for smell transferring.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and specifically relates to a polymer material with a controllable odor playback function and a preparation method thereof. It has the characteristics of a multi-layer structure and a layered preparation. It can be used according to the characteristics of flavor volatilization and use environment. Adjust the structural characteristics of each layer, so as to achieve the purpose of controlled release of odor gas. Background technique [0002] Liquid flavors have multi-component characteristics, and the volatilization characteristics of each component are different, which leads to the rapid volatilization of the top notes in the natural state of the liquid flavors. After long-term use, the flavor quality is incomplete and the odor components are missing, which greatly reduces the use time of the flavor. A single component or structure is often limited to the liquid storage or odor transmission...
