Abstract
AbstractThe contribution deals with the comparison of microwave heating and conventional oil bath heating. Silicon dioxide nanoparticles were grafted with MPTMS under acid conditions. Those particles contain a polysiloxane shell with physically adsorbed and chemically bound fractions which can be separated by Soxhlet extraction. The resulting fractions were analyzed with TGA and MALDI‐TOF MS; one to determine the amount of physically adsorbed and chemically bound fractions and the other to get deeper insight into the polysiloxane structures. Furthermore, it was our aim to clarify which fraction can be visualized using MALDI‐TOF MS. Our results show that the ratio of chemically bound MPTMS is higher when using microwave heating, but the same structures in the physically adsorbed fraction were built in both cases.magnified image
