Abstract

The diffusion behavior of poly(ethylene glycol) (PEG) in N-isopropylacrylamide (NIPAAm) hydrogels was investigated using confocal Raman spectroscopy with regard to temperature (25°C, 30°C and 35°C), PEG concentration (10 and 40 wt.%), PEG molecular weight (2,000 and 12,000 g/mol) and addition of the compatible solute ectoine (0.1 and 2 wt.%). Swelling and shrinking of the gels was observed by means of confocal Raman spectroscopy. The swelling behavior of NIPAAm gels in aqueous solutions of PEG and ectoine was found to resemble the swelling behavior in pure water with regard to temperature, i.e., the gel shrinks with increasing temperature. However, the presence and concentration of PEG and ectoine influence the swelling behavior by lowering the volume phase-transition temperature of the gel and facilitating shrinking. In some cases, a re-swelling of the gel was observed after the initial shrinking at the onset of PEG diffusion, which can be explained by PEG changing the chemical potential in the gel phase as it diffuses into the sample allowing the water to re-enter. The expulsion of water from the gel during shrinking and the so-caused increase of PNIPAAm and PEG concentrations in some cases led to the PEG diffusion seemingly being faster in more shrunken gels despite of their higher diffusion resistance.

Fußnoten
1
At higher concentrations of KCl and NaCl the water activity coefficient decreases again.
 
2
When the wavelength of the emitted photon is the same as the excitation wavelength the effect is called Rayleigh scattering. It is approximately three orders of magnitude stronger than Raman scattering and would dominate the spectrum if it were not removed by a suitable spectral filter.
 
3
The glass is necessary to give the gel films mechanical stability and to thus facilitate handling. The covalent bonds between gel and glass prevent the gel from being washed off during the diffusion experiments.
 
4
The gels were washed thoroughly with deionized water after synthesis (see “Synthesis of gel samples”) to remove oligomers and unreacted monomers that could diffuse out of the network. The network itself was covalently bonded to the carrier glass and could not diffuse into the PEG solution.
 
5
The concentration of PEG outside the hydrogel film remained constant within a fluctuation of max. ± 0.48 wt.% for all experiments as it was supposed to.
 
6
The extent in the other directions was of no interest here since a uniform concentration was assumed parallel to the sample surface.
 
7
The two systems were fitted separately so as not put too much weight on the binary system PEG/water, yet the similarities between A and C as well as between B and E suggest that a common fit would yield good results as well.
 
8
For very high concentrations of ethanol, acetone and PEG the gel swells again, but not to the same value as in pure water [29].
