Fabrication of retro-reflective polyurethane via covalently embedding with amino-functionalized glass microspheres

Glass Microspheres

“…The manuscript of Zakir Hossain et al[150] highlighted a simple cost-effective one-step process for fabricating porous calcium phosphate-based glass microspheres with varying control over surface pores and fully inter-connected porosity via a flame spheroidisation process. Tian et al[151] presented a new point of view to develop retro-reflective polyurethane (GMPU) composed of polyurethane and amino-functionalized glass microspheres (NH 2 -GM), the latter was founded to be chemically bonded onto the PU successfully. According to Araque et al[152] composite films of PHB, HGM and PP-g-MA were developed through the melt intercalation technique to evaluate the properties of the materials by means of morphological, thermal, and mechanical properties.…”
