Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work, all belong to the protection scope of the present invention.

[0031] In this embodiment, the composite hydrogel of the present invention is mainly made of the following raw materials by weight:

[0032]

[0033]

[0034] Among them, with the combination of two components of complete alcoholysis type polyvinyl alcohol and partial alcoholysis type polyvinyl alcohol, they are easy to form micropores in water, and the air permeability of the polyvinyl alcohol composite film is controlled by adjusting the different ratios of the two components. The principle is to use the good water so...

Abstract

The invention relates to the field of high polymer materials, in particular to a composite hydrogel, a composite hydrogel film and a preparation method and application thereof. The composite hydrogelis mainly prepared from complete alcoholysis type polyvinyl alcohol, partial alcoholysis type polyvinyl alcohol, a natural polymer material, salicylic acid, a surfactant, a silane coupling agent, nanographene oxide, zinc oxide whiskers, nano titanium dioxide, water and the like. A water-soluble polymer base material is adopted, water serves as a solvent, the natural polymer material is added, harmful chemical substances or stimulating substances are avoided, and environmental friendliness and safety are realized; by adoption of salicylic acid, nano titanium dioxide and zinc oxide whiskers asan antibacterial agent and an anti-ultraviolet agent, great escherichia coli antibacterial effects are achieved, and ultraviolet harms are effectively reduced; the composite hydrogel film is excellentin mechanical performance and available for antibacterial and ultraviolet protection application, such as touch screen sterilization, textile material bacterium resisting, ultraviolet prevention andthe like.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a composite hydrogel and a preparation method thereof. Background technique [0002] Polymer hydrogels are a class of polymers with a three-dimensional network structure that can be swelled by water but insoluble in water. It can achieve a sensitive response to external stimuli through volume swelling or contraction. Polyvinyl alcohol (PVA) hydrogel is one of the most widely used hydrogels. PVA not only has the properties of water absorption, water retention, sustained release and sensitive response to external stimuli of general hydrogels, but also has excellent properties such as low toxicity, biocompatibility and transparency due to its special properties. and other fields have a wide range of applications. [0003] Textile materials mainly include cotton, hemp, silk, wool and various chemical fibers, which are susceptible to degradation and aging due to various factors. T...
