Chemistry is a solid degree, though prospects within chemistry aren't great... not in terms of salary anyway. Lab work tends to pay surprisingly poorly for the skill and education required.
Materials science is quite a niche degree - certainly within the engineering field. Materials engineers - and the various subfields that you can also go into, such as metallurgy, corrosion engineering, welding engineering, etc. - are certainly extremely useful in industry and sought after, though you may not find that many graduate positions compared to the main engineering disciplines.
