Synthesis of vinyl trimethyl silane and acrylic acid modified silica nanoparticles as corrosion inhibition protocols in saline medium

•Biodegradable polymeric inhibitor was prepared from mesoporous silica as a host material.•At 100 ppm inhibitor concentration, low corrosion rate (∼4.0–9.0 × 10−3 mm/year) was achieved.•The inhibitor showed high inhibition efficiency at high temperatures.
