We reported an optimal material for embedding chemoresponsive dyes based on modified commercial PDMS. A new approach to impart hydrophilicity to H-PDMS in an unique step was developed by addition of tetraethyl orthosilicate (TEOS) and in absence of basic or acid aqueous mixtures or hydroxyl-compounds during the PDMS coating process. This incorporation significantly enhances the performance of PDMS-based devices for sensing applications. New colorimetric sensors for passive detection and in situ discrimination of volatile amines have been obtained. The limit of detection achieved was 1.5 mg m−3 for both, dimethylamine and methylamine, suitable to control real working atmospheres. This work has been supported by a PATENT P201300436 (Campíns-Falcó et al. [1]).

Ons berig 'n optimale materiaal vir inbedding chemoresponsive kleurstowwe gebaseer op gemodifiseerde kommersiële PDMS. 'N Nuwe benadering tot hydrophilicity om H-PDMS dra in 'n unieke stap is ontwikkel deur die byvoeging van tetraetiel orthosilicate (Teos) en in die afwesigheid van basiese of suur waterige mengsels of hidroksiel-verbindings tydens die PDMS coating proses. Dit inlywing aansienlik verhoog die werkverrigting van PDMS-gebaseerde toestelle vir sensing programme. Nuwe kolorimetriese sensors vir passiewe opsporing en in situ diskriminasie van vlugtige amiene verkry. Die beperking van die opsporing bereik was 1,5 mg M-3 vir beide, dimethylamine en Methylaminen, wat geskik is vir regte werk atmosfeer te beheer. Hierdie werk is ondersteun deur 'n patent P201300436 (Campíns-Falco et al. [1]).
