Effect of polymerisation by microwave on the physical properties of molecularly imprinted polymers (MIPs) specific for caffeine

Abstract

Synthesis of Molecularly Imprinted Polymers by microwave irradiation is significantly affected by applied power.

Selective Recognition of Gallic Acid Using Hollow Magnetic Molecularly Imprinted Polymers with Double Imprinting Surfaces

“…The final weight loss of HMMIP was 12.63% when the temperature continued to rise to 900 °C. Therefore, the prepared HMMIP had higher thermal stability, which was not only superior to the MMIP prepared in this paper, but also superior to some previous reports on MIP [ 25 , 34 , 35 , 36 , 37 ].…”

A highly efficient microwave-assisted synthesis of an LED-curable methacrylated gelatin for bio applications

“…This frequent reorientation leads to the strong rotation, movement, agitation, collisions, and friction between species. [39][40][41][42][43] Subsequently, the supremacy of the MWA method can be described comprehensively by the dielectric properties and relaxation time of the reactants and solvents. [39][40][41][42][43] Dielectric constant (3 r ) is a vital quantity to estimate and compute the reactivity of materials under the MW conditions.…”

[39][40][41][42][43] Dielectric constant (3 r ) is a vital quantity to estimate and compute the reactivity of materials under the MW conditions. [40][41][42] According to the SS1 section and eqn (S1) mentioned in the ESI, † 3 r can be calculated by using the dipole moment (m) as an electronic descriptor which commonly describes the polarity of components and the distribution of the electrons on the molecules.…”

[50][51][52][53] Generally, molecules with large m have higher electronic interactions with other molecules, more spatial molecular conformers, and a higher tendency to be excited rotationally in the presence of the MW eld, leading to better performance in chemical reactions.…”

“…According to several publications over the past 30 years, one of the most important methods to increase the chemical reaction rate is the irradiation of microwave (MW). 37,[39][40][41] Based upon the widespread studies, the main advantages of the MW-assisted (MWA) synthesis over the conventional heating methods include the reaction time and side products reduction, uniform and homogeneous reaction, selectiveness, and subsequently higher yields under milder reaction conditions which permit energy and time saving towards the green and sustainable chemistry. [39][40][41][42][43] Irmak et al obtained GelMAs by coupling MA and gelatin under the MW condition and expressed some benets over the conventional method like the signicant reduction of the reaction and puri-cation time as well as the required MA concentration due to the increased reaction efficiency.…”
