Silanized surfaces, proposed surface structure

All of the model surfaces were used within 4 days of preparation. Figure 1 illustrates the proposed surface structure of the silanized surfaces as well as the untreated silica surface (26.27). 

Strong adhesion of ceramics is difficult in most cases. Treatment of ceramic surfaces with chemicals such as silane coupling agents or hydrogen fluoride has been proposed [1], but the adhesion has not been improved enough for practical applications. Furthermore, no studies have been done on the relationship between the monomer structure and the adhesion of ceramics. 

Dense polymer structures with well-controlled compositions and dimensions are preferentially grown from a wide range of surfaces by atom transfer radical polymerization (ATRP). Different bromo-terminated molecules ranging from silanes, thiols, or disulfides to aromatic moieties derived from diazonium ions " have been proposed to initiate the polymer growth.
