Preparation of hybrid aerogels with excellent vacuum drying performance

Under the strong support of the Ministry of Science and Technology and the National Natural Science Foundation of China, scientists from the State Key Laboratory of Polymer Physics and Chemistry at the Institute of Chemistry, Chinese Academy of Sciences, for the first time prepared a flexible low density organic-inorganic hybrid gas by simple vacuum drying technology. gel. This aerogel material with simple preparation method, excellent performance and easy surface functionalization is of great significance for the practical application of aerogel.
Researchers first prepared a bridged silsesquioxane precursor containing thioether segments through molecular design and dried directly at room temperature to obtain aerogel, which greatly simplified the aerogel preparation process. The aerogel obtained by vacuum drying completely retains the initial size of the wet gel, not only has the excellent characteristics of the aerogel prepared by the traditional method, but also has good elasticity, and can be compressed repeatedly without generating for 30% deformation. Permanent deformation; Even after soaking in ethanol or aqueous solution, the structure remains unchanged after vacuum drying. This provides the possibility of functional modification of the aerogel skeleton surface by a simple wet chemical or physical dipping method.
Aerogels are one of the lowest density synthetic materials known to date, and have attracted wide attention due to their extremely low apparent density and thermal conductivity, high porosity and specific surface area. However, the aerogel's porous structure and extremely low density lead to its poor mechanical strength; in addition, the commonly used supercritical drying process has complicated procedures, long cycle, low yield and high cost, which restricts the practical application of aerogels.

Electric Water Kettle

Electric water kettle

If you are new to the concept of using an electric kettle, you might be overwhelmed by the variety of electric kettles that are displayed on the store shelves and have difficulty deciding which one would be the best to suit your individual needs or desires. This introduction will give you some basic information about some of the features that are available on various types of electric kettles so that you can make a more informed decision when choosing one for use in your home.

Features:

Spend few minutes to boil : After 5 minutes, hot water will finish for you to drink.

3 protection functions : The on/off button is on the handle, making it easy to turn the kettle off when you pick it up. A concealed heating unit reduces the amount of buildup in the kettle.

It will be a problem when you forget to close the button.Once the water boils the kettle shuts itself off.Do not have to worry about damaging it by letting it run dry. When water runs dry,It will cut the electric by itself.

Multiple Cups: Water can be loaded to 1.8Liter.

Materials :

Food grade stainless steel, more healthy and hygienic. PP handle wieh heat insulation material provides scald resistance. Durable controller performance with 360 degree rotation cordless base design.

OEM & ODM service : Try best to support you during production and provide better after-sales service.Enhance your brand popularity.

Application:

Make a cup of tea.

Boil eggs.
