acrylic pressure-sensitive adhesives - Opis:
- Pressure-sensitive adhesives (PSA) are a group of adhesive-based macromolecular polymers which are characterized by good (satisfying the requirements of industrial) adhesion and cohesion; high temperature stability during use, excellent aging resistance and constant tear strength. In 1935, the concept of self-adhesive glue, wherein the obtained self-adhesive product of the invention R. Stanton Avery, was firstly developed. From many types of adhesives, the most common adhesives are acrylics pressure-sensitive adhesives [1–3]. In most cases, self-adhesive adhesives do not exhibit good conductive properties, whereas conductivity grades are classified in the group of insulators. In order to improve their conductive properties, studies have been conducted on the modification of polymers in adhesive compositions, where at least one of the components exhibited conductive properties (e.g. polymers with conjugated π-bonded polymers along polymeric chains). However, the best effects were obtained by adding conductive fillers such as metal (copper, aluminum), specially modified soot, nanotubes or graphene, carbon fibers, metallized glass and conductive fibers. This allowed the creation of electrically conductive compositions characterizing by conductivity in the range from 10–2 to 102 S/cm. This relatively high conductivity is the result of the percolation of conductive filler molecules into an insulating matrix or tunneling between electrically conductive molecules [10, 11]. Acrylate pressure-sensitive adhesives with conductive fillers have found a number of important industrial applications, especially in the electronics industry. Pressure- sensitive adhesives, such as self-adhesive tapes or adhesive films, are used as heating elements, sensors or conductive gums. Due to their good performance, they can be used to connect solar panels or glue small components in the microelectronics industry. They also can be used to discharge static charges from the surface – used as flexible drainage connections – especially in places where the spark is undesirable and can be dangerous. They are used as heating elements [10, 12, 27].
