    The Mechanism for 3-Aminopropyltriethoxysilane to Strengthen the Interface of Polycarbonate Substrates with Hybrid Organic–Inorganic Sol-Gel Coatings (1997)
    Springer
    Journal of inorganic and organometallic polymers and materials 7 (1997), S. 203-216 
    Details
    ISSN: 1572-8870
    Keywords: Aminolysis ; sol-gel coating, 3-aminopropyltriethoxysilane ; bisphenol-A polycarbonate ; CR-39 ; interface compatibilizer ; primer
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract An aminolysis mechanism is proposed to explain the enhanced adhesion between the interface of a bisphenol-A polycarbonate substrate with an alkoxysilane containing sol-gel coating when 3-aminopropyltriethoxysilane (3-APS) is used as a primer. Both a model solution study and surface analyses of polycarbonate substrates exposed to 3-APS indicate that the latter reacts with the carbonate groups in the polycarbonate chain by forming urethane linkages. With 3-APS bonded to the substrate, a sol-gel coating can be chemically bonded to the substrate through hydrolysis of alkoxysilane groups and subsequent silanol condensation. Consequently, enhanced adhesion between the sol-gel coating and the substrate is achieved.
