  • The wetting properties of an uncured epoxy resin on both clean and oiled, galvanised steel have been studied. Since the polymer is very viscous at ambient temperature, and also with an aim to simulate industrial conditions, the spreading of drops of resin during a heating cycle (temperature increase at $10^{\circ}C/min$) was recorded and analysed. On clean steel, a contact angle, ${\theta}$, vs time, t, plot shows sigmoidal behaviour, whereas on the oiled substrate, spreading almost ceases in an intermediate stage. This strange behaviour is attributed to significant oil absorption by the polymer.

  • In this article, the characterization of the interface of hybrid composites was discussed. Interfacial interaction in organic/inorganic hybrid composites, especially silica-containing hybrids can be characterized by fluorescence spectroscopy, small angle X-ray scattering (SAXS), scanning electron microscopy (SEM), atomic force microscopy (AFM), and $^{29}Si$ NMR spectroscopy measurements.

  • 점착제는 경피흡수제제(transdermal drug delivery system, TDDS)의 중요한 구성요소 중의 하나이다. TDDS용 점착제는 일반적인 점착제의 역할 외에도 부착되는 피부에 적합해야 하고, 이것에 포함되는 약물 및 첨가제들과 양립하면서 약물의 전달을 효과적으로 지속해야한다. 본 총설에서는 흔히 사용되는 TDDS용 점착제인 polyisobutylenes, polyacrylates, silicones와 최근에 개발된 제품들을 소개한다.
