Problems solved by technology

[0008] This shows that the above-mentioned existing wound dressing obviously still has inconvenience and defects in product structure, manufacturing method and use, and needs to be further improved urgently
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve

[0068] The first embodiment of the present invention discloses a skin wound healing material, which comprises: a fluorine-containing hydrophobic film with a first surface and a second surface opposite to each other, the hydrophobic film is gas permeable but liquid impermeable properties; at least one biocompatible macromolecule covalently bonded to a part of the first surface of the hydrophobic film; wherein the contact angle to water of the first surface formed with the biocompatible macromolecule is 40 degrees or less, more preferably 10 to 40 degrees, more preferably 20 to 30 degrees. When the contact angle to water is 20-30 degrees, the effect of leaving no scars is better. The second surface is hydrophobic, and its contact angle to water is more than 100 degrees.

[0069] In the above embodiment, the at least one biocompatible polymer is selected from polymers without charged groups, polymers containing diionic groups, and polymers containing pseudo-diionic groups. At l...

Abstract

The invention pertains to a skin wound healing material and a manufacturing method thereof. The skin wound healing material comprises a fluorinated hydrophobic film and at least one biocompatible macromolecule, wherein the fluorinated hydrophobic film is provided with a first surface and a second surface which are opposite to each other, the fluorinated hydrophobic film has air permeability and liquid impermeability, the at least one biocompatible macromolecule is formed at part of the first surface of the hydrophobic film by covalent bonding, and the water contact angle of the first surface where the biocompatible macromolecule is formed is below 40 DEG.

Description

technical field [0001] The invention relates to a skin wound healing material and a manufacturing method thereof, in particular to an amphiphilic fluorine-containing polymer skin wound healing material and a manufacturing method thereof. Background technique [0002] The total surface area of ​​the skin is about 1.5 to 2.0 square meters. It can maintain the temperature and moisture of the human body, and avoid being damaged by bacteria and the external environment. Skin can be divided into epidermis, dermis and subcutaneous tissue according to structure. Wounds occur when the skin is injured, and the process from wound occurrence to healing can be divided into three stages: inflammatory phase, fibroplasia phase, and maturation or remodeling phase. Whether the process of these three stages is smooth or not determines whether the wound will heal well, or the recovery will be poor and the condition will deteriorate. [0003] Wound dressings need to have (1) accelerated wound ...
