The coatings had the metallurgical bonding with the matrix, and there was an evident transition layer within the matrix.
The degree of reinforcement depends on the lateral size, dispersion state and orientation of the nano-filler within, and its bonding to the matrix.
At up to 100 °C on DTA, the physically bonded water within the matrices evaporated, and there was physical dehydration of C3A ettringite between 140 and 180 °C, ettringite and aluminate-based hydrates between 270 and 330 °C, and aluminate-based hydrates at around 570 °C.
Of course, some of the enzyme is also bonded to the matrix surface, but most is trapped within the bulk.
A semi-permeable polyurethane film was bonded to the matrix.
The signal intensity depends upon radiation absorption and subsequent alterations for example in the hydrogen bond content within in the matrix.
Wherever these fibers intersect within the matrix, hydrogen bonds hold them together, making the material stiff.
In cementitious nanocomposites, CNTs can act as effective bridges to minimize and limit the propagation of micro-cracks through the matrix, under the conditions of well dispersion of the CNTs within the matrix and good bonding between the CNTs and the surrounding hydrated cement matrix.
A controllable adhesive disbonding mechanism can be achieved by incorporating, and then activating, functional additives located within the matrix of an adhesively bonded joint.
Morphological, chemical, physical and mechanical characterization of the natural fibers were correlated with the resulting bond properties within the embedding matrix.
That is due to the stronger intermolecular interactions such as H- bonding and Van Der – Waals interactions, experienced by the intercalated citrate anions within the matrix.
