A multi-block copolymer comprises at least one hydrophilic collagen-like block and at least one silk-like block. The silk-like block comprises an amino acid sequence ((GA)mGX)n (SEQ ID NO: 10), wherein G is glycine, A is alanine, m and n are at least 2. X is an ionizable amino acid. The ionizable amino acid can be inducedle to bear a positive charge or a negative charge. The ionizable amino acid bearing the positive charge is preferably histidine and the one bearing the negative charge is preferably glutamic acid.
