In the field of material science frequently polymeric substances with an high cross link degree are called networks. This is due to the fact that polymer molecules resemble chains of many replicas basic polymer component (the monomer).
Cross links generates bonds either between different points of the same chain or between different chains so structuring the material microscopic arrangement like a sort of network.
The most famous process of this kind is rubber vulcanization. This creates many cross links based on a bridge made by three sulphur atoms and transforms completely the properties of natural rubber generating a sturdy, elastic and durable material.
What else can I help you with?
Why covalent-network substances are insoluble in all common solvents?
Covalent-network substances have strong covalent bonds that hold their atoms together in a three-dimensional network structure. This network structure makes it difficult for common solvents to break the bonds and dissolve the substance, leading to their insolubility in most solvents.
What substance is an example of a network solid?
An example is the boron nitride. Another is silicon dioxide.
What are pore spaces that are joined to each other?
Pore spaces that are joined to each other create a network of interconnected voids within a material or substance. This interconnected network allows for the movement of fluids or gases through the material, influencing its permeability and porosity. Examples include interconnected pore spaces in soil or rock formations.
What is the difference between a large molecule and a covalent network substance?
What's in a name? The division between the two is arbitrary at the extremes of large molecules although even extremely large molecules may have a definite known molecular formula (for instance proteins), whereas a covalent network may only be known as multiple repeats of a simple unit, such as (SiO2)n )
What is a substance with a high melting point in which all the atoms are covalently bonded?
Diamond is a substance with a high melting point in which all atoms are covalently bonded. Diamond's structure consists of a network of carbon atoms, each bonded to four other carbon atoms in a tetrahedral arrangement, resulting in a strong covalent bond network that gives diamond its exceptional hardness and melting point.
What substance element is an example of a network solid?
Diamond.
Why covalent-network substances are insoluble in all common solvents?

Is water molecular or network?
Water is a molecular substance. It is composed of molecules made up of two hydrogen atoms and one oxygen atom. Each water molecule is independent and not interconnected in a network structure.
What substance is an example of a network solid?
An example is the boron nitride. Another is silicon dioxide.
What is a network bond?
So a network covalent bond or macromolecular bond is basically a bunch of covalently bonded atoms. Imagine a diamond structure or crystal structure that keeps expanding but a model only shows a building block of the substance. So like a brick wall to a brick.
What is an element as a substance which cannot be separated into simper substances?
Diamond. Diamond is composed strictly of carbon, covalently bonded to one another creating a covalent network, making it the hardest substance in the world. Also, graphite of your pencil is composed strictly of carbon, except that the structure is different than diamond.
Is the cytoplasm composed of the cytoskeleton?
No, the cytoplasm is a gel-like substance within cells that contains various organelles and molecules. The cytoskeleton is a network of protein fibers that provides structural support and helps with cell movement. The cytoplasm surrounds and contains the cytoskeleton.
What is a network password given by the network?
network
What are pore spaces that are joined to each other?
Pore spaces that are joined to each other create a network of interconnected voids within a material or substance. This interconnected network allows for the movement of fluids or gases through the material, influencing its permeability and porosity. Examples include interconnected pore spaces in soil or rock formations.
Bacterial cell walls contain a unique substance called?
peptidoglycan. This substance provides structural support and protection to the bacterial cell by forming a mesh-like network around the cell membrane. Peptidoglycan is a key component of bacterial cell walls and is absent in the cell walls of other organisms, such as plants and animals.
What is meant by the term securing your perimeter network security?
your perimeter network is the network you operate such as you have the internet and your network your network is your perimeter
Difference between telecom network and computer network?
A Telecom network is a Telephone and Cable TV Network. A computer network involves computers.
