In this manuscript, the authors described a method to create 3D-printable ABS-MOF composite materials for hydrogen storage. This research greatly improves the processibility of MOF and will potentially expand the applications of such materials. However, the contribution of MOF in the hydrogen adsorption performance improvement in ABS was rather limited. This manuscript demonstrates acceptable overall quality. The manuscript should be considered for publication after the following concerns are addressed. 1. The introduction section is lacking a brief review of the state-of-art of hydrogen storage materials. It is necessary to have this information so that the author can compare their work to the existing materials in the results and discussion. 2. There are a few typos in the Method section, such as "DCS". 3. No information about how many repetitions of the mechanical tests were done was given in either the Method section or in the table notes. Was that a single measurement? What does the error in the mechanical measurements mean? The authors have to clarify. 4. Since there was inconsistency in the material homogeneity, did the materials from the different batches have sufficiently consistent hydrogen adsorbing performance? 5. Why hydrogen adsorption performance of pure ABS is missing? Why the ABS-MOF adsorption data were immediately extrapolated after a sharp transition? Was there a difficulty in further measurement? 6. Due to the limited performance improved as shown by the data, the current conclusion is to some extent extravagant. It should be rephrased in a self-restrained manner.
