    What is Cross linking and its functions?

    In the world of SEO (Search Engine Optimization), Cross-linking, in simple words, can be defined as linking between two sites.

    Both the sites that are linked do not need to be owned by the same person. Cross-linking, in a way, helps both (or all the sites that are cross-linked) the sites in rising up the search engine ranks.

    it is necessary that all the content needs to be different in both or all the sites that are cross-linked.

    The function of cross-linking in a site can be termed as follows:

    1. Increase in traffic: Getting users to visit a website through cross-linking can help in the increase in traffic on both of the sites

    2. Unique content: t is essential and necessary for both the sites to have unique and original content.

    3. Different content but related topics
    : One of the most critical functions of cross-linking is to provide different, original content related to the topic that the user is searching for.

    Cross-linking is an art of linking between two websites, irrespective of their owners. ... It basically provides the users with reference sites that have similar or relevant content as the one they are viewing or more information about the topic they are reading about.

      Cross-link is a bond which links one polymer chain to other. ... Cross linking increases the molecular m*** of a polymer. Cross-linked polymers are important because they are mechanically strong and resistant to heat, wear and attack by solvents.

        Cross-linking refers to the process of linking two or more polymer chains together, either within the same molecule or between different molecules. This process creates a three-dimensional network structure within the polymer material, imparting specific properties and characteristics. Cross-linking can occur through various chemical or physical means, depending on the type of polymer and the desired outcome.

        Functions of cross-linking in polymers include:
        1. Enhanced Mechanical Properties: Cross-linking increases the strength, toughness, and stiffness of polymers, making them more durable and resistant to deformation under stress. This is particularly important in applications where mechanical strength is critical, such as in automotive parts, construction materials, and medical devices.
        2. Improved Thermal Stability: Cross-linked polymers generally exhibit higher thermal stability, maintaining their structural integrity at elevated temperatures. This property makes them suitable for use in high-temperature environments, such as in electrical insulation, aerospace components, and industrial applications.
        3. Reduced Solubility and Swelling: Cross-linking decreases the solubility and swelling behavior of polymers in solvents and liquids. This enhances their resistance to chemical degradation, moisture absorption, and environmental factors, making them more suitable for use in harsh conditions.
        4. Controlled Porosity: Cross-linking can be used to control the porosity of polymer materials, allowing for the creation of membranes and filters with specific permeability properties. This is important in applications such as water purification, gas separation, and drug delivery systems.
        5. Biocompatibility and Bioactivity: Cross-linked polymers can be engineered to be biocompatible and exhibit specific bioactive properties, making them suitable for use in medical implants, tissue engineering, and drug delivery devices.
        6. Improved Electrical Properties: Cross-linking can enhance the electrical insulation properties of polymers, making them suitable for use in electrical and electronic applications, such as cables, wires, and insulating materials.
        7. Dimensional Stability: Cross-linking helps maintain the dimensional stability of polymers by reducing their tendency to shrink, swell, or deform over time. This property is important in applications where precise dimensions and shape retention are required, such as in molded parts and components.
