Conventional approaches often rely on top\u2010down methodologies that require high energy inputs and sophisticated equipment, and offer limited scalability. Bottom\u2010up strategies, particularly block copolymer (BCP) self\u2010assembly, have emerged as attractive alternatives, yet they generally yield static structures whose dimensions are dictated by BCP macromolecular parameters. In this work, we introduce an additional level of tunability by exploiting the thermoresponsiveness of one block within an amphiphilic BCP. Poly(N\u2010isopropylacrylamide)\u2010block\u2010(2\u2010acetoacetoxyethyl methacrylate), P(NIPAM\u2010\n                    <jats:italic>b<\/jats:italic>\n                    \u2010AEMA), was synthesized and self\u2010assembled at the air\u2010water interface using a Langmuir\u2010Pockels trough. Surface compression and temperature guide the evolution of the monolayer from continuous films to spherical nanodomains. Atomic force microscopy (AFM) and grazing\u2010incidence small\u2010angle x\u2010ray scattering (GISAXS) show that compression mainly controls the spacing between nanodomains, whereas temperature changes their size, spacing, and order through thermoresponsive reorganization of the interfacial film. Above the P(NIPAM) lower critical solution temperature, the nanodomain array becomes more regular, consistent with temperature\u2010induced reorganization of the copolymer at the interface. These results identify thermoresponsive BCPs as useful platforms for tunable interfacial self\u2010assembly and provide a simple route to stimuli\u2010responsive nanostructures at fluid interfaces.\n
