In the present study a scientific approach is presented to experimental and theoretical minimized friction of polyamidimide (PAI) coatings for electrical wire insulation. The copolymers of polydimethylsiloxane (PDMS) and polyamidimide (PAI) developed in this study enable the formulation of self-lubricating PAI coatings with exceptionally lowered coefficients of friction (CoF). The corresponding coating surface shows a self-patterning of PDMS domains, covering the PAI matrix polymer. PDMS microphase separations are immobilised through a covalent bond to the polyamidimid. The use of the developed PAI-PDMS copolymers in PAI coatings results in specific self-structuring surfaces. The structuring of the PAI matrix with PDMS-microphase seperations is depending on the copolymer structure, PDMS segment length and PDMS content in the PAI PDMS copolymer. Surface patterning arises parallel to the reduction in the friction force for the concerning copolymer coating surface. PDMS-microphase separations show ‘liquid like characteristics and can be described as “tethered liquid” in a first approximation.Alternatively to the PAI-PDMS copolymers nonaqueous PDMS-microgel dispersions were developed. These may be inserted directly into conventional PAI coating systems. In this study a simple synthesis for the production of corresponding PDMS-microgel dispersions in n-methyl-pyrrolidone (NMP) is presented. Coating formulations containing appropriate PDMS microgel dispersions exhibit significantly reduced friction.
