Hydroxypropyl cellulose (HPC) was purchased from Tokyo Chemical Industry Co., Ltd. (TCI) and the molecular parameters are as follows: number- and weight-average molecular weights, 9.9 × 104 and 1.5 × 104 respectively; degree of substitution, DS = 1.4 and MS = 3.9,28 (link) where DS and MS denote an average number of substituted hydroxyl group and that of introduced hydroxypropyl group, respectively. Methyl acrylate (MA), methyl methacrylate (MMA), ethyl acrylate (EA), ethyl methacrylate (EMA), isopropyl methacrylate (iPMA), and 4-acryloylmorpholine (ACMO) were obtained from TCI and used after passing through a column packed with activated alumina (Wako Pure Chemical Industries, Ltd. (Wako)). Dehydrated pyridine (Wako), propionic anhydride (TCI), 4-dimethylaminopyridine (DMAP) (Wako), 2-hydroxy-2-methylpropiophenone (HMPPh) (Sigma Aldrich Co. LCC.) were used without further purification.
2 hydroxy 2 methylpropiophenone hmpph

Cotton-derived fibrous cellulose was obtained by cutting and milling of Whatman filter paper No. 5 (GE Healthcare Life Sciences Corp.). Sulfuric acid (Nacalai Tesque, Inc.) and polyethylene glycol (PEG; molecular weight = ~20,000, Wako Pure Chemical Ind., Ltd.) were used as received. Monomers, HEMA (Wako Pure Chemical Ind., Ltd.) and AA (Nacalai Tesque, Inc.), were purified by vacuum distillation before use. A photopolymerization initiator, 2-hydroxy-2-methylpropiophenone (HMPPh; Sigma-Aldrich), and a cross-linking agent, ethylene dimethacrylate (EDM; Tokyo Kasei Kogyo Co., Ltd.), were used without further purification.
Calcium chloride dihydrate (CaCl 2 •2H 2 O) and ammonium carbonate ((NH 4 ) 2 CO 3 ) were purchased from Nacalai Tesque, Inc. and used as ion sources for mineralization. A low-molecular-weight PAA (L-PAA; average degree of polymerization (DP) = 25, Sigma-Aldrich) was used as a precipitation inhibitor in the salt solution of ion server [25, 37] . Other conventional chemicals were purchased from Wako Pure Chemical Ind., Ltd. or Nacalai Tesque, Inc. and used as received.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
