PMMA surface configuration

Figure 24.8 Temperature dependence of surface configuration change rate of PMMA in air and in water.

Figure 8.2. Target configuration for dynamic tensile fracture experiments on rock. PMMA buffers and windows were not used on those rocks with an acoustic impedance comparable to PMMA. Velocity for these tests was measured at the rock-free surface.

Functional groups may already be present in the polymer structures of the chemicals or can be added to the surface by various chemical treatments, depending on the molecular configuration of the specific polymer required for modification. For example, the polymer PMMA, which consists of methyl ester groups, can be chemically modified by a simple reduction reaction to alcohols, with lithium aluminum hydride in ether-based solutions, followed by the widely used organosilane...
