Structure and Thermophysical Characteristics of Gas-Filled Polymers

Thermal resistance and durability of insulation systems of building structures, firstly, provide comfort in insulated rooms and, secondly, provide protection of the building structure entirely from negative atmospheric influences and largely depend on the properties of thermal insulation. Many properties of heat-insulating materials and, in particular, average density, thermal conductivity, water absorption, vapor permeability, thermal conductivity, etc. are determined by the properties of the polymer matrix (type of polymer, method of polymerization and porization), as well as porosity and structure the porosity of these materials. The purpose of the research presented in the article was to study the relationship between the structure of gas-filled polymers and their thermophysical characteristics and to verify the solutions obtained by testing the properties of materials. Based on the position that the thermal resistance and durability of insulation systems of building structures largely depend on the properties of thermal insulation, the requirements for the properties of thermal insulation materials are set out. It is substantiated that the thermophysical characteristics of heat-insulating materials and, in particular, thermal conductivity, are determined by the properties of the polymer matrix (the type of polymer, the method of its polymerization and porization), as well as the porosity and porosity structure of these materials.
