      abstract     = {Most commonly polydimethylsiloxane (PDMS) elastomer
                      (silicone) is obtained from prepolymer liquid by
                      cross-linking reaction (curing) at room temperature or
                      assisted by external heating. However, in special cases,
                      such as medical applications, it could be useful to cure the
                      elastomeric material selectively and / or without
                      external heat. An ability for customized curing can be
                      controlled by selection of special type of fillers, such as
                      metal particles or carbon nanotubes for curing routed via
                      Joule heat, magnetic induction or electromagnetic microwave
                      radiation. There are number of reasons for microwave curing
                      to be preferred: microwave curing does not require heat
                      conductivity of the surrounding medium, microwave energy can
                      be directly delivered to select part of the material, this
                      also allows for energy saving. Dielectric (internal) heating
                      by microwave radiation is not efficient for pristine PDMS
                      due to non-polar nature of this substance. Higher chemical
                      polarity additives to PDMS could facilitate internal
                      heating. We test silver nanoparticles (Ag NPs) for using as
                      internal heating agent for PDMS elastomer kit (Sylgard 184).
                      A set of general properties of the resultant
                      PDMS / AgNPs composite material, including dynamic
                      mechanical analysis (DMA), water wetting contact angle,
                      adhesion to glass and optical spectroscopy of the filled
                      PDMS are evaluated herein. The obtained composite materials
                      exhibit a significantly higher work of adhesion, a lower
                      viscoelastic modulus and slightly higher wettability. With
                      time of microwave treatment and consequently cross-linking
                      of the material those parameters head towards or approach
